According to ablogtophone, State Route 28 or SR-28 and PA-28 is a state route in the U.S. state of Pennsylvania. The road forms the northeast exit route from Pittsburgh and is a freeway until Kittanning, a distance of 40 miles. The total route continues to Brockway and is 157 kilometers long.

Travel directions

SR-28 begins at the interchange with Interstate 279 and Interstate 579 just north of downtown Pittsburgh. The road then runs as a narrow freeway to the northeast, parallel to the Allegheny River, with 2×2 lanes. The highway follows the course of the Allegheny River and crosses Interstate 76 northeast of Pittsburgh, the Pennsylvania Turnpike, the Cleveland to Philadelphia toll road. The highway then runs through some of Pittsburgh’s last suburbs, and reaches the regional town of Kittanning, where US 442 is served.crosses the main route from Butler to Altoona. Here, SR-28 crosses the Allegheny River, ending the highway section. The road then runs double-numbered with SR-66 to Bethlehem, where SR-66 runs north, while SR-28 continues to run northeast. Brookville crosses Interstate 80, the highway from Cleveland to New York. Not far after, SR-28 ends at US 219 in Brockway.


The State Route 28 number was assigned in 1927 to the route from Pittsburgh to Kittanning, and on to Brockway in 1928, creating the current global route.

Beginning in 1964, work began on the conversion and construction of State Route 28 as a freeway between Pittsburgh and Kittanning, the Allegheny Valley Expressway. Much of the highway was completed in the mid-1970s, but the last section, between Exit 13 & 15, did not open to traffic until 1985.

Between 2009 and 2014, the southernmost 2 miles in Pittsburgh was converted to a 2×2 lane freeway. Originally there were two T-junctions with bridges over the Allegheny River here. The redesigned highway formally opened to traffic on November 17, 2014. It was originally planned to build a 2×3 lane highway here in 1963, but this was never implemented.

State Route 147 or PA-147 is a state route in the U.S. state of Pennsylvania. The road forms a north-south route across the bank of the Susquehanna River in the center of the state, from Duncannon to Milton. The northernmost part is a freeway, the rest a minor road. State Route 147 is 94 kilometers long.

Travel directions

State Route 147 is largely a minor road on the east bank of the Susquehanna River. This is a rural route that leads through small towns. The starting point is at Duncannon on US 22, not far north of the capital Harrisburg. US 15, located on the west bank, is the primary thoroughfare in this area. The landscape consists of wooded mountain slopes and meadows. The largest population concentration is halfway along the route at Sunbury and Northumberland, which also connects to US 11. Further north, State Route 147 becomes a freeway that becomes Interstate 180. at I-80to William Sport. The highway section is 15 kilometers long, the main place on the route is Milton.


The highway portion in the Milton area was constructed concurrently with I-180 to Williamsport, construction of the portion comprising State Route 147 began in 1970 along Milton to Chillisquaque. This part was opened to traffic in 1972. Later, US 15 was upgraded over the west bank of the Susquehanna River as it was the primary route between Harrisburg and Williamsport. In the Milton area, however, this did not mesh well with US 15 on the west bank and State Route 147/I-180 on the east bank.

Central Susquehanna Valley Thruway

The Central Susquehanna Valley Transportation (CSVT) Project was completed between May 2016 and July 2022, the northern portion of which included a new bridge over the Susquehanna River between US 15 and State Route 147 and a minor upgrade of PA-147 to near freeway chillisquaque. The new connection opened on July 7, 2022.
