SCOTT AIR FORCE BASE, ILLINOIS

3/12/2025

1 GENERAL

1.1 BACKGROUND Scott Air Force Base is one of the oldest Air Force bases in service, established in 1917 as Scott Field. Scott Drive was originally a two-lane Illinois State Route (two-lanes on East side) with ditch drainage. By 1944, the roadway had doubled in size when two-lane southbound travel lanes were added to the west, ultimately forming the boulevard. In 1947, Scott Field officially became Scott Air Force Base (SAFB). As SAFB continued to develop west of the current alignment, few improvements to storm water facilities to accommodate growth of SAFB were made. Similarly, little consideration was given to north-south non-motorized (bicycle and pedestrian) mobility. Thus, several deficiencies exist today including deteriorating pavement, substandard drainage facilities, inconsistent typical section, and lack of bicycle and pedestrian facilities.

1.2 OBJECTIVES This project is to complete full depth patching along Scott Drive to repair sections of pavement in poor condition.
