Wabash Ave. to close for construction

Wabash Ave. will close for construction between Wabash Spur Drive and 300 feet West of Edlen Lane for approximately 10-12 weeks, weather dependent, starting Monday May 7, 2018.  During this closure, access to Wabash Avenue from Edlen Lane will also be closed. Access to Sonderen Street and E. Terra Lane will remain open for those residents entering and exiting the Country Life Subdivision. The closure is required to allow for replacement of the box culvert under Wabash Avenue at Edlen Lane, replacement of the water main, and reconstruction of the Wabash Avenue pavement in this area. Motorists are encouraged to avoid this area during the closure if at all possible. A detour route will be signed to aid motorists in navigating around the closure.
