All ramps that have been closed during the reconstruction of the Highland Park Bridge interchange with Route 28 reopened Wednesday, the Pennsylvania Department of Transportation announced.

Three ramps — southbound Route 28 to the bridge, Freeport Road to northbound and southbound Route 28, and from the bridge to the Freeport Road exit to Aspinwall — reopened after being closed for various times during the construction season. The work is part of a $47.3 million project to add separate exit lanes from the highway to the bridge and improve safety at merge points on the bridge.

The only remaining traffic restriction at this point is a lane restriction on southbound Route 28 approaching the bridge.

Additional work, including a traffic light for motorists crossing the bridge from Highland Park to the highway, remains, and there could be additional restrictions. Golden Triangle Construction Co. is expected to finish the project before the end of the year.

When the project is finished, motorists will have free-flowing traffic from Pittsburgh’s North Side to Kittanning with no traffic lights.
