At Breezewood, I-70 exits the turnpike (making use of a short stretch of the old alignment of the Pennsylvania Turnpike), while I-76 bypasses the Rays Hill and Sideling Hill tunnels along a new alignment built in the 1960s. I-76 also bypasses Harrisburg and Reading both to the south. The major features of this section are more mountains with the Tuscarora Mountain Tunnel and then a double tunnel (Kittatinny/Blue Mountain) prior to PA 997 near Shippensburg. I-76 intersects I-81 (indirectly) in Carlisle, Pennsylvania, then I-83 and I-283 near Harrisburg. The Susquehanna River Bridge is a new six lane bridge that was constructed in 2003 using precast segments that replaced an older bridge across the Susquehanna River. At Valley Forge, I-76 diverges towards Philadelphia, but the turnpike (as I-276) bypasses it to the north.
