Motorists will have to contend with ramp closures off Ewing road through October. 

The Allegheny County Airport Authority soon will begin a $950,000 project to improve the Interstate 376 and Ewing Road intersection in the township, according to a PennDOT  announcement.

The project will include construction of a new roundabout  for the roadway's I-376's on-and-off ramps.  Construction will begin on June 27, weather permitting. 

On-and-off ramps for the eastbound I-376 business loop will be closed until the project's planned late-October completion.  The primary contractor is Imperial-based Golden Triangle Construction Co. Inc. 

The authority obtained a highway occupancy permit for the project. 

PennDOT has provided the following suggested detour routes for motorists:
