Traffic is being re-routed tonight as City Utilities workers investigate the cause and ultimately repair the source of unstable pavement in the 2200 block of Spy Run Avenue, just south of State Boulevard.

Crews were called to the scene shortly after 5 p.m. today after the pavement began to buckle in a portion of the road.  City Utilities crews are locating the source of the unstable ground at this time.

At around 9 p.m. all four lanes of traffic were closed. Local traffic should use Main Street and Sherman Boulevard or Columbia Avenue and North Anthony Boulevard. Wells Street is under construction and not recommended as detour. Truck traffic will use a detour on Coliseum Boulevard. The Indiana Department of Transportation will release more information about the truck detour.

Crews will be working through the night, and all four lanes are expected to be closed tomorrow morning. Drivers who use Spy Run will need to find an alternate route until the street is reopened. City Utilities does not know when the lanes will reopen.
