HOLLIDAYSBURG, BLAIR COUNTY - Construction work on a busy overpass got underway Tuesday morning.
Traffic on Frankstown Road has been reduced to one lane each way in between Lakemont and the Pleasant Valley Shopping Center.
Penn-DOT officials suggest drivers plan extra time for delays.
The repairs and improvements made to the bridge that crosses I-99 are scheduled to be finished by June.
Similar upgrades are part of an overall plan that includes the I-99 interchanges at Frankstown Road, Plank Road, 17th Street and Tyrone. Crews will also replace guiderails along the highway between the Plank Road Exit and the 17th Street Exit.
Work on all projects should be completed in September.
Meantime, on Wednesday, construction crews will place single-lane northbound and southbound restrictions on Route 453.
The work zone runs from the I-99 on/off ramps intersection of Route 453 to the intersection with Route 4027 (Pennsylvania Avenue).
The project will consist of milling, bridge deck repairs and the placement of a new concrete deck overlay.
Work is anticipated to be completed by mid-July.
It's part of a $1.7-million contract that will rehabilitate five bridges in Tyrone Borough and Snyder and Antis Townships. This project is funded through the American Recovery and Reinvestment Act (ARRA).
