Paving work takes place this week on 3 Westmoreland County roads. Tomorrow crews will be on Leedstown Road between Route 3 and Parrish Lane. The work moves to Mt. Holly Road/Erica Road on Thursday then on Friday workers will be on Carmel Road near Route 202. Work hours for each project are 7:00 a.m. to 7:00 p.m. Flagging crew will alternate, one-way traffic in the work zones so plan for some delays.
