Upon leaving Springfield, Illinois, Route 66 travelers must decide which of two alignments to travel — the pre-1930s alignment or the later alignment, which continued as Route 66 until 1977. Both have their unique history, interesting stops, and photo opportunities.
The pre-1930s two-lane alignment meanders through Chatham and Auburn — where you can see a piece of brick alignment — before moving on to Thayer, Virden, Girard, Nilwood, Carlinville, Gillespie, Benld, Sawyerville, and Staunton. South of Staunton, the road rejoins with the later alignment.
One of the oldest and most scenic segments of Route 66 in Illinois, portions of this path pre-date the Mother Road as it travels along the old Pontiac Trail. Named for Ottawa Chief Pontiac, this road was the main pathway between Chicago, Illinois and St. Louis, Missouri, in the early 1900s.
In 1918, a bond issue was passed to construct “hard roads” in Illinois, and the old trail was designated as SBI-4 (State Bond Issue).
Initially, it began in the western Chicago suburb of Cicero and was fully completed by 1924. Roughly paralleling the Chicago & Alton Railroad, this old chunk of pavement represents the first hard portion of the Mother Road and is a testament to the birth of the interstate highway system. In its earliest years, it was used by hundreds of soldiers returning from World War I, then by Chicago mobsters during the Prohibition era, leading the road’s reputation as “Bloody 66” and the birth of the Illinois State Police.
In Springfield, it entered to the east of the Illinois State Fairgrounds before traveling south through the capital and meandering through downtown streets until following South Grand Street to what is now Chatham Road and exiting the city on the southwest side.
Along this route, travelers will see old brick road sections, concrete paths, abandoned routes, and old bridges, as well as numerous small towns where life goes by at a much slower pace. These small towns provide numerous historical looks at the past, and the countryside is filled with interesting barns, homesteads, and farms.
Illinois Route 4, North of Auburn (1921-1932) – A bypassed portion of old Route 4 north of Auburn, Illinois, is listed in the National Register of Historic Places. This segment consists of a 1932 1.53 mile long brick road and a 1921 Portland cement road. Both are well-preserved examples of Route 66’s early years in Illinois, illustrating early highway era construction methods.
These sections served as part of Route 66 until 1930, when the realignment of the Route 66 south of Springfield rerouted traffic to the less populated eastern side through Litchfield to speed up the flow of traffic by avoiding as many towns as possible.
The concrete section consists of a 1,277 foot long, 16-foot wide Portland cement dating from 1921. After Route 66 was realigned in 1930, this section briefly reverted to its State Route 4 designation before being abandoned in a 1932 relocation of the State road.
The second 1.53 brick section was incorporated into the 1932 modifications and resurfaced with brick at the same time. Today known as the Auburn Brick Road, it contains two original single-span concrete bridges over Little Panther Creek constructed in 1920 and paved with brick in 1932.
This segment was added to the National Register of Historic Places in 1998. It is located on Curran and Snell roads north of Auburn, Illinois.
To reach the concrete 1,277-foot section, travel south on Highway 4 from Chatham to Alpha Road and turn west. The segment is located on Alpha Road between Highway 4 and Curran Road. The Auburn Brick Road is located between Chatham and Auburn on Snell and Curran Roads. Heading south from Chatham on Highway 4, turn west on Snell Road, curve south and turn into Curran Road before rejoining Highway 4.
Route 66, Girard to Nilwood (1919-1931) – Underscoring the fast-paced evolution of Route 66 in Illinois, this segment was designated as a part of the Mother Road in 1926 but was quickly replaced in 1930 with a major realignment to the east. Constructed in 1920 as part of old State Route 4, this short-lived section of Illinois Route 66 is typical of the engineering and construction methods of the post-World War I era. This was a time of genuine transition in road construction, often combining horse and mule with state-of-the-art trucks and machinery in World War I. The road’s cross-section included two eight-foot-wide lanes with 4-7 foot wide gravel shoulders. The Portland cement slab was generally six inches thick.
Although cracked in places, its current concrete pavement is original. The road segment retains five of its original concrete box culverts and an original 1920 single-span concrete bridge. An interesting piece of the pavement can be seen just south of Nilwood, Illinois, where turkey tracks were imprinted within the original concrete when it was poured. After more than 80 years, they can still be seen today.
