Where Route 66 crosses the Colorado River

Topockis a small community located on Route 66. Topock was the point where Route 66 crossed the Colorado River. After crossing the harsh and arid Black Mountains or the Mojave Desert, travelers came to a spot with plenty of water.

It is best known for its bridges across the Colorado River, especially the Trails Arch Bridge (1916 - 1947 US 66 Bridge), a historic site.
See the 1908 water tower with a U.S. 66 shield on it and drive The Historic Route 66 Back Country Byway from Kingman to Topock.

Don't miss the attractions (beaches, nightlife, and the original London Bridge) in Lake Havasu City, south of Topock.

About Topock, Arizona

Facts, Trivia and useful information

Elevation 456 ft (139 m). Population est 1,500 (2020).
Time zone: Mountain (MST): UTC minus 7 hours. Summer (DST) no DST⁄ PDT (UTC-7).

The "modern" Topock is a small village, an unincorporated community in western Mohave County, on Route 66 in northwestern Arizona, next to the community of Golden Shores. Neither of these two towns have any Route 66 context, they are much more recent.

"Classic" Topock was located to the south of these villages, right beside the River and next to the bridges (This map shows where).

Topock's History

black and white late 1800s photo of Capt. Mellon

Captain John A. Mellon (1841-1924) Credits.

The Colorado River valley has been inhabited for the more than 10,000 years. It was the home of the Mojave people; whose name is a deformed version of and "macave", along or beside, and "aha", water = beside the water (of the Colorado river).

The Mohave lived south of what is now Hoover Dam along the Colorado River well beyond Parks Dam.

Arizona was part of the Spanish colonies in America but it was never settled. After its independence from Spain in 1821, Mexico "inherited" the territory but after its defeat in the 1846-48 War with the U.S., ceded it to America.

Capt. Lorenzo Sitgreaves explored the area in 1851 and Lt. Edward "Ned" Fitzgerald Beale surveyed a wagon route from Ft. Smith in Arkansas to California, passing just north of what is now Topock during his journey.

The Atlantic & Pacific Railroad (later the Atchison Topeka and Santa Fe Railroad) reached the area in 1882 and built a bridge across the Colorado River north of Topock (learn more below: Topock's bridges). In 1890 a definitive bridge (Red Rock Bridge) went up at Topock.

At that time, there was a steamer paddleboat service in the Colorado River and one of its veteran officers was Captain John "Jack" Alexander Mellon (1841-1924). He had come to the Colorado River from New Brunswick in 1863 and worked for George Johnson's Colorado Steam Navigation Line. His surname, deformed to "Mellen" became the name of the railway station at Topock.

There was a ferry landing next to the station. A post office opened there from 1903 to 1909. However, by 1915 the station was named "Topock" and the area around it adopted it as the local place name.

The Name: Topock

The word Topock (TOH pahk) is also found in San Bernardino County, California and is a Mojave word "tuupák" derived from the verb "Tapák-", "to drive piles".

Another version says that it comes from "ahatopok" which means "bridge", for the railroad bridge built there in 1890.

The locals pronounce it "Toe-pock".

In the 1910s, the National Old Trails Highway (N.O.T.) laid its route from California to Kansas, and the road crossed the Colorado at Topock, first using a ferry but by 1916 the historic Trails Arch Bridge was built.

The N.O.T roadmap spelled it "TOPOC" and pointed out that it was a "small village with good accomodation in all lines. Topock Bridge connects Arizona and California."

Route 66 was aligned along the N.O.T. in 1926 using the same bridge and during the 1930s many farmers escaping the "Dust Bowl" drought, crossed it westbound seeking jobs in California, as starkly portrayed in John Seteinbeck's 1939 book "The Grapes of Wrath". The movie based on the book, included a shot of Route 66's bridge across the Colorado River.

In 1952, Route 66 was realigned, bypassing Sitgreaves Pass on the Black Mountains and the mining town of Oatman. Instead it ran along level ground close to the railroad, to Kingman through Yucca.

Interstate 40 crossed the river in 1966 and replaced U.S. 66 in this area. The small settlement of Topock was bypassed as few cars left I-40 at Exit 1.

What is now known as Topock (and has the post office with that name) is next to Golden Shores a resort town, 5 mi. north of "old" Topock, haven to sun-seeking retirees and others fleeing the cold winters in the north.

Route 66 was aligned across the Black Mountains in 1926 it linked Kingman and Topock via Oatman, a rich mining town.
At Topock the highway crossed the Colorado River (we describe the bridges it used, in detail, further down).
The highway was realigned following the Santa Fe tracks along Sacramento Wash, via Yucca, in 1952. This was flat ground and avoided the dangerous mountain road with hairpin bends and Sitgreaves Pass between Oatman and Kingman.

See this map of the US 66 alignment from Kingman to Topock (1926-52). We describe it in detail in the link below (Kingman to Topock):

Route 66 reaches the Colorado River Bridges

Historic context, the classic Route 66 in Topock

In 1946, just after World War II ended, and just as the large flow of veterans began their new lives along the Western Coast, many of them moving west along Route 66, Jack DeVere Rittenhouse wrote his book, "A Guide Book to Highway 66". It gives us an insight into what it was to drive along the Mother Road during its heyday. Rittenhouse mentions the following about Topock:

Gas; grocery; few cabins; garage for light repairs; limited facilities Rittenhouse (1946)

.

All of these places have long since gone due to the changes introduced in the highways by the different bridges built to get across the Colorado River and by the construction of I-40.

Topock Then and Now

The image below shows Chevron and a Mobil gas stationsm Les Crinklaw's towing, and a cafe with cabins (now I-40 runs across it).

A Description of Old Topock

The original Route 66 from Oatman curved southwards in a wide arch and passed under the Santa Fe railroad. The underpass was built in 1944 (perhaps to make it safer for the wartime traffic (1).

Water Tower

On the south side of the tracks was a small depot with a rusting water tower built by the Santa Fe railroad in 1908. It has a Route 66 painted on it. It is 24 feet diameter and 43 feet high with a conical roof. It contained raw water for the steam engines (2).

The gas stations (Gone)

They were originally lined up towards the Arches Bridge, south of the underpass, but in 1947 realigned along the new course of US66 that curved west after the underpass towards the Red Rocks Bridge.

The picture below looks west towards California, to the right (north) are some gas stations, and in the distance the Red Rock bridge. The railroad embankment is to the right, out of view.

This picture was taken just before the construction of the freeway began in the 1960s.

The Needles

In the two views from the underpass, the mountains known as "The Needles" can be seen in the distance. They are part of Topock and its charm and have appeared as the backdrop in several movies.

Grapes of Wrath and The Needles

The book by John Steinbeck and the movie it inspired, directed by John Ford, portrayed the tragic story of an Oklahoma family, the Joads, who lost their farm during the Great Depression and migrated to California seeking new opportunities.

In this Pulitzer Prize-winning work, Steinbeck (who later won the Nobel Prize in Literature) depicts their tragic journey (along Route 66). He also coined the phrase "Mother Road", referring to U.S. 66.

There is a long a scene (watch video further down) in the 1940 movie showing the Joads as they reach Topock and park by the Colorado River bridge, and then cross it. The still below show part of this scene and it shows "The Needles" beyond the curve in the Colorado River:

Easy Rider

The Needles and the Red Rock bridge appear in the 1969 movie "Easy Rider" with Peter Fonda and Dennis Hopper as two bikers Wyatt and Billy. The movie has many scenes shot in Arizona (Flagstaff, Bellemont). Below is a still with the jagged Needles and the old bridge in the opening scenes of the movie; watch video above.

Topock and Hollywood Trivia: The Fondas

The Coloraro River and Topock link actor Henry Fonda, who was filmed here in "The Grapes of Wrath" and his son Peter Fonda did so in the "Easy Rider".

The Geology of The Needles

These mountains are about three miles south of Topock. They have a peculiar profile with sharp jagged peaks and pinnacles. Their height ranges from 1200 to 1600 feet.

They were named by Lt. A. W. Whipple during his expedition in 1854 to find a route for a transcontinental railroad along the 35th parallel. He wrote, describing the terrain:

the worst yet. It was a confused mass of gorges, precipices, and serrated crests several thousand feet high Whipple (1854)

Here the Colorado River runs between to abrupt mountain ranges: The Needles and the Chemehuevi Mountains; it formed the narrow Topock Gorge with its sharp Devil's Elbow turn.

The mountains have a complex geological history including massive basalt flows and intrusions, and a gigantic eruption of a volcano in the southern Black Mountains that covered the area with tuff some 19 Million years ago. Dikes can also bee seen, they are the remains of the lava that solidified in the chimneys of long gone volcanos.

PG&E Topock compressor station

On the south side of the freeway is a natural gas compressor station beside the old Arch Bridge. It was built to pump the gas from gas fields in Texas to northern California.

It is their pipeline that saved the old Trails Arch bridge: it carries the gas pipeline across the Colorado River.

Nowadays there are no visitor services at Topock. There is a restaurant, bar, gift shop, and swimming pool at Topock66 Resort and Topock Marina used by boaters to refuel, both of them located on the north side of the railroad, next to the Topock Marsh area.

The bridges in Topock

Five bridges were built to cross the Colorado River south of Needles:

  1. The First Railroad Bridge, gone, 1883 - 1890
  2. The Red Rock Railroad Bridge, 1890 - 1947 Railroad Bridge (later 1947-66 U.S. 66 Bridge)
  3. The Trails Arch Bridge, 1916 - 1947 Road Bridge)
  4. The New Red Rock Railway Bridge, since 1945)
  5. The Freeway Bridge, after 1966

Looking east from California into Arizona, the three bridges.

The freeway hadn't been built when the picture was taken. Topock can be seen in the distance, in Arizona.

First Railroad Bridge

The Atchison, Topeka and Santa Fe Railroad, (AT &SF) which controlled the Atlantic and Pacific Railway (A&P), built its line across Arizona from Kingman (1882) towards the Colorado River to reach Needles, California. They built a bridge and completed it on August 3, 1883, reaching Needles.

First bridges: destroyed by floods

The site for the first bridge was a "Eastbridge", 3 miles south of Needles. There the local workers drove pilons into the soft river bed to support the wooden bridge they would build across the Colorado River. The bridge, completed in August 1883 was washed away by the spring flood season.

Red Rock Bridge (1890)

A new bridge was built in 1884, and again in 1886 and 1888. The floods and the unsuitable location for the bridge site (sandy clay soil) led the engineers to relocate the bridge further south in 1890.

They chose a point with solid bedrock foundations beyond the marshes and the mouth of the Sacramento Wash, at a narrow spot at Beal, CA, facing Mellen Arizona (now known as Topock) where there was a solid rock foundation for the bridge. There they built a steel cantilever bridge, the "Railway Red Rock Brige".

The steel cantilever bridge

The bridge cost over $460,000 which is more than $15 million 2022 dollars) and was America's longest cantilever bridge.

Cantilever bridges

A cantilever bridge uses cantilevers which are structures that extende horizontally, from a supporting point, at one end. These cantilevers can range from simple beams to steel or concrete frames. Steel cantilevers can span more than 1,500 ft. (460 m) and are easily built.

It could carry 3,000 lbs. per linear foot, but trains and their cargo increased as time went by so the bridge was reinforced in 1901 to carry heavier loads.

To carry even heavier trains, a support pier was added in the middle of the span thus the bridge was no longer a cantilever bridge.

It spanned the river alone until 1916 when, a few hundred yards downstream, a new bridge was built for automobiles.

Trails Arch Bridge

Listed in the National Register of Historic Places in 1988.

White slender arches of bridge across Colorado River

The Topock Bridge, Arizona & California. Credits

The cars that drove along the roads of the 1910s, crossed the Colorado River using the Needles Ferry. But a flood razed the ferry in 1914 so the cars crossed the river using the railroad's Red Rock Bridge: planks were laid across the tracks and the cars crossed between trains.

There was a bridge on the "Ocean-to-Ocean" route at Yuma, but the Los Angeles to St. Louis National Old Trails Highway also required a bridge across the Colorado River

In 1914, the states of Arizona and California, the US Bureau of Indian Affairs and San Bernardino County agreed to build a bridge.

The structure is a steel arch bridge with a "cantilever system" where the arch was assembled in two halves on each side of the river and then hoisted into place and linked together with a ball-and-socket central hinge.

At 800 ft. (243 m) in length and with a span of 600 ft. (182 m), it was the longest arch bridge in America until 1928.

The bridge was completed on Feb. 20, 1916 and carried the traffic of the N.O.T. highway. In 1926, U.S. 66 was aligned across it and remained so until 1947 when it was replaced by the Red Rock Bridge which the AT&SF railroad had just stopped using.

Its deck was removed in 1948 and a natural gas pipeline was laid across it; it is still in use.

We marked the course of the 1926-47 Route 66 from Topock AZ to California across this bridge with a pink line in our custom map of Route 66 in AZ.

Viewing the Trails Arch Bridge

From the California side of the river you can get a good view the old Arch Bridge from this vantage point (Map and Directions from Topock AZ), there is a concrete billboard and a parking space. The Billboard says "Welcome, Turn Right Next Exit" with a Route 66 shield.

The black and white image is a still from themovie "The Grapes of Wrath" showing the Joads on U.S. 66 crossing the Colorado River along the steel arch bridge in 1940.

New Red Rock Railroad Bridge

The heavy military cargoes during World War II led the AT&SF railroad to plan and build a new bridge just north of the original one.

It was completed in February 1945: a high level double-track bridge. This bridge is still in use today.

Route 66 Red Rock Bridge: Carried vehicles after 1947

The Trails Arch Bridge was a very narrow bridge and only one lane crossed it, it also had a sharp 90° turn on the Californian side. It had a low carrying weight (11 tons); as trucks carried heavier loads a new bridge became necessary.

When the railway completed the "new Red Rock Bridge" the "old" bridge was modified to accommodate U.S. 66 trafic in 1947 and continued carrying traffic until it was replaced by the I-40 bridge in 1966. The old steel structure was removed in 1978.

We marked the course of the 1947-66 Route 66 from Topock AZ to California across this bridge with a dark blue line in our custom map of Route 66 in AZ.

These two aerial photographs reflect the changes over the years:

This aerial photograph taken in 1947 shows, from top (north) to bottom (south), the three bridges that crossed the Colorado River at that time. The 1969 aerial photo shows all bridges, including the one carrying I-40.

Interstate I-40 Bridge

The Interstate system launched in 1956 reached the Colorado River in 1966 and a new bridge was built to carry it across the river: a four laned steel girder structure supported by concrete piers.

The old Cantilever bridge was abandoned and closed to traffic.

It was finally dismantled in 1978 and you can see its plaque at the nearby Needles Museum.
