State transportation officials say they will try a few tweaks to relieve traffic at the U.S. 27 construction project at Signal Mountain Road, but residents will still have to to deal with delays until the end of March, when the ramp is complete.

Traffic at the Signal Mountain Road exit has snarled the daily rush hour on U.S. 27 northbound since the new exit ramp opened Jan. 26.

Tennessee Department of Transportation Commissioner John Schroer said Thursday the total widening project is the second largest TDOT has ever taken on, and he asked residents to remain patient.
