Motorists will encounter a detour in Derry Township and a lane restriction in the New Alexandria area this week, according to PennDOT officials.
Single-lane, nighttime restrictions are scheduled to begin Wednesday on Route 22 in New Alexandria and Salem Township.
The nightly restrictions are to be in place between 8 p.m. and 6 a.m., ending on Saturday morning. They will allow crews to replace compression and strip seals on three bridges that carry Route 22 over Route 66, Beaver Run and Loyalhanna Creek.
At 7 a.m. on Wednesday, a section of Hickory Avenue will close in Derry Township, while Norfolk Southern Railway crews replace some track.
The closure, between First Avenue and Third Street, is expected to end by 7 p.m. on Friday.
A marked detour will direct motorists along Fourth Avenue, Leo Street, Chestnut Street and Route 982.
