Major delays and lane restrictions are in store for drivers who use Route 30 in Lancaster County this week. PennDOT officials say work will begin Tuesday and last through Thursday at the Centerville Road Interchange Improvement Project in East Hempfield Township. Work is scheduled for 9 a.m. to 2 p.m. but some night-time lane restrictions could also be in place. The officials say you should try to plan an alternative route as heavy delays are expected.
