Traffic will be stopped for up to 15 minutes at a time near the Oakmont Service Plaza on the Pennsylvania Turnpike between 10 p.m. today and 9 a.m. tomorrow in the eastbound direction and between 10 p.m. Saturday and 9 a.m. Sunday in the westbound direction.

As many as six stoppages will be necessary in each direction while a contractor installs a new water line that's attached to a new Oakmont Country Club pedestrian bridge, part of a turnpike reconstruction and widening project in that area.
