Crews from the Tennessee Department of Transportation will shift traffic on U.S. 27 South beginning Tuesday night.

The traffic shift will result in a new traffic pattern beginning Wednesday morning on U.S. 27 South that will "significantly" affect the 4th Street accessibility to and from U.S. 27 South, according to TDOT's Jennifer Flynn.

During the traffic shift on Tuesday night, there will be temporary lane closures on U.S. 27 South in the area of the Olgiati Bridge and 4th Street.

Motorists are urged to avoid the area on Tuesday night between 7:00 p.m. and 6:00 a.m. If you travel in this area, be sure to stay alert and obey all signage as the traffic shift is implemented.

After the traffic shift is completed on Wednesday morning, motorists wishing to access 4th Street from U.S. 27 South will take a new ramp at the south end of the Olgiati Bridge and turn left onto 4th Street to enter the downtown area. Motorists who normally use 4th Street to access U.S. 27 South from the downtown area will be detoured to MLK Blvd. where they can access U.S. 27 South. The existing ramps to and from U.S. 27 South at 4th Street will be closed to allow room for construction of a new bridge and a new section of U.S. 27 South. Motorists need to exercise caution when traveling through the construction zone and pay close attention to all posted signage.

This configuration will remain in place until future phases of construction are completed. Access to U.S. 27 North from 4th Street will remain unchanged during this time.

This work is weather dependent; if weather or unforeseen circumstances delay the traffic shift, it will be rescheduled for a later date.
