The History of Williamsville

The central part of Illinois has been inhabited for at least 11,000 years, the rivers of this region were explored by French trappers in the mid 1600s, but only during the first years of the 1800s did settlers move out to the vast prairies.

Founded as Benton in 1853 when the railroad reached the area (after the U.S. sentator from Missouri Thomas H. Benton). The name was later changed to Williamsville and incorporated in 1884.

The name: Williamsville

The town was named to honor Col. John Williams (1808-1890) a Springfield merchant. He fought with Abraham Lincoln in the Black Hawk War (1832) and they became close friends.

Route 66 was aligned through the downtown district in 1926 and then moved west in 1940, bypassing it. In 1976 I-55 cut off the town completely.

Things to see in town

Reaching Williamsville

You can get to Williamsville using Historic U.S. 66 (here under the freeway I-55), take Exit 109

Williamsville US 66 in 1946

In 1946, researching for his classic Guidebook of U.S. 66, Jack Rittenhouse drove the Mother Road from Chicago to L.A., he mentions Williamsville:

"Pop. 649... The town is a quarter of a mile off US 66 (L). There is a garage in the town, but no gas station or other facilities on the highway"

It is evident that he drove along the "Bypass" 66 as the town was off to the left.

Williamsville Public Library and Museum

217 North Elm St. Williamsville

To your right is the library with its great "distance-to" sign. It is brand new and has an interesting collection covering local history.

Elm Street was the original 1926 alignment through Williamsville until the 1940 "bypass" was built further west.


Ahead, to your right is the now closed "Hilarious Route 66 Gas Station":

Hilarious Route 66 Gas Station


117 North Elm St. Williamsville

Also known as "Old Station", it is a 1930's gas station with vintage gas pumps and classic signs from the "old days". A great place for a photograph. It is now closed (since 2016) and up for sale.

Ahead, to your right, on the corner of Elm and Main, are two brown Historic route 66 road signs, one points right to the "main" (Bypass) alignment the other points ahead to the "spur". Across the street is the old Railway depot:

Williamsville Railroad Depot and Box Cars

102 South Elm St.

The original depot was built in 1854. There is a wayside exhibit with two Union Pacific box cars and some US 66 mementos. This is its Street View.

To your left, along Main Street, crossing the tracks is the Downtown:

Williamsville’s Downtown

Main St. Williamsville

On Main and Pine (NE corner) is an interpretative sign on the SW corner is another one. See its Street View.

Drive south either along South Elm or along the "Bypass" 66 (Old Route 66) to see the old Fawn’s Service Station:

Fawn’s Service Station

500 S. Old Rte. 66, Williams

This was the location of Fawn’s Service Station and the now gone Route 66 Café it was at the southern tip of Williamsville bypass.

In 1945 Wilbur Fawn bought the Standard Oil service station that had been owned by Fran Finch since 1941 he added a tow truck. The building is still standing, with a two-door garage. It had three pumps. See Another Vintage photo of the gas station.

In 1976 I-55 was finally completed and the old US 66 was cut off. The station closed in 1984. The defunct Route 66 Café was just east of the service station.

Below is a "Then and Now" sequence of the building, which is quite unchanged:

Historic Route 66 in Williamsville

1926-1940 US 66

The first alignment of Route 66 entered the town along Elm St. and then ran parallel to the railway south into Sherman. It is shown in Green in the Google map.

1940 realignment

1940 USGS map of Williamsville US66

1940 USGS map of Williamsville

A safer alignment was needed (acccidents in the towns were increasing), so a bypass was built around the town.

As you can see in the 1940 USGS map of Williamsville, Route 66 opened into two alignments at Williamsville, one went through the town (the original 1926 alignment), the other newer one, around it. Each was a 2-lane highway both met to the south of town, where Finch would build his gas station the following year (later Fawn's Standard Oil gas station).

During WWII the whole of US 66 began improving and a four-lane freeway began being built. It was finished in the early 1950s, before the Internet system was implemented.

The 1958 USGS map of Williamsville shows all the traffic heading down the main "Bypass" alignment. I-55 would later be built to the west of this four-lane divided highway.

It was then that the road through the downtown area became the "Spur" alignment, shown in Green in the map.

When I-55 was finished in 1976 the freeway cut off the old "Bypass" so it now is a dead end south of town (Pale Blue).

From Northern side of Sherman (where Sherman Blvd. meets the northbound lanes of I-55) to Williamsville the alignment of Route 66 is now beneath the freeway so we have marked it in Red in the Google map.
