CUMRU TWP., Pa. -

Motorists who make the northernmost stretch of Interstate 176 part of their regular route will have to find a temporary way to travel, starting Thursday night.

PennDOT announced Wednesday that it will close the highway between Route 724 and Route 422, also known as the West Shore Bypass, in Cumru Township from approximately 8 p.m. Thursday until 6 a.m. Monday.

Traffic will be detoured onto Routes 724, 10, 222 and 422 through the weekend.

That's the bad news. The good news is the closure will allow crews to remove concrete barriers and set up new traffic patterns, which will open all lanes of I-176 for much of the project's remaining work, officials said.

The $14.7 million improvement project, begun in August 2012, is entering its fifth and final stage, which entails erecting signs, paving the highway, installing drainage inlets and painting lines. The work is set to wrap up in December.

When the project is complete, I-176 will feature an additional collector/distributor lane in each direction for ramp traffic between the 422 and 724 interchanges and new bridges over 422, the Norfolk Southern Railroad train tracks and the Thun Trail.
