The route from Lafayette over Lookout Mountain will soon require a detour. The Chickamauga Creek Bridge on Highway 136 West will be closed on October 16, for replacement. The contract allows builders up to a year to replace the two-lane bridge. But hopes are to have it finished by next summer. In the meantime, the DOT only uses state routes for detours. That means West-bound traffic on 136 would turn South on 341 at the four-way stop and cross over to Highway 193. A shorter route would be to run South at 341 and take a right on Halls Mill Road. It dead ends at Kensington Road which comes back to 136 on the other side of the bridge work.
