Railroad crews are replacing the railroad bridge on the north side of East Main Street/T15 at Competine Creek on the east side of Knoxville.  That’s according to Knoxville Public Works Director Jeff May.  He says the project will require the closing of one lane of East Main Street/T15 at different times during construction and the pubic should expect delays when the road is restricted to one lane.  The project will be completed sometime in July.
