The Pennsylvania Turnpike has scheduled a four-hour overnight closure of one section of the highway and a four-hour interchange closure for this weekend.
The turnpike will close in both directions between Bedford (Exit 146) and Breezewood (Exit 161) from 1 a.m. to 5 a.m. Sunday for demolition of a bridge at mile 153.
The on- and off-ramps at the Beaver Valley interchange (Exit 13) will be closed and traffic will be detoured using the New Castle interchange (Exit 10) from 11:59 p.m. Saturday to 4 a.m. Sunday. A section of Route 18 also will close with a posted detour for local traffic.
A planned closure from Butler Valley to Allegheny Valley early Sunday was canceled.
