A 1.3-mile stretch of old Route 66 south of Lake Springfield in Springfield, Ill., was named to the National Register of Historic Places effective May 12, reported the National Park Service in a weekly newsletter.
The designation was expected after the state submitted its application to NPS.
A story a few weeks ago from the Springfield Journal-Register had some details about the road:
Preservationists believe the road is the longest drivable section of the original Route 66 remaining in Illinois. […]
The road, 16 feet wide compared to 24 feet for modern two-lane roads, is often used by farm equipment and as a commuter route for people who live southeast of Springfield.
