Selinsgrove /ˈsiː.lɪnzˌɡroʊv/ is the largest borough in Snyder County, Pennsylvania, United States. The population is estimated to be 5,761 for the 2020 Census.
Selinsgrove is geographically located in the middle of the Susquehanna River Valley in Central Pennsylvania, along U.S. Routes 11 and 15, 45 miles north of Harrisburg and 5.7 miles (9.2 km) southwest of Sunbury. It is the home of Susquehanna University.
U.S. Route 13 or U.S. Highway 13 (US 13) is a north–south United States Numbered Highway established in 1926 that runs for 518 miles (834 km) from Interstate 95 (I-95) just north of Fayetteville, North Carolina, to US 1 in the northeastern suburbs of Philadelphia, Pennsylvania, near Morrisville. In all, it traverses five states in the Atlantic coastal plain region. It follows the Atlantic coast more closely than does the main north–south U.S. Highway of the region, US 1. Because of this, its number is out of place on the general U.S. Highway numbering grid, as it should be running west of US 11 but does not. Its routing is largely rural, the notable exceptions being the Hampton Roads area in Virginia and the northern end of the highway in Delaware and Pennsylvania. It is also notable for being the main thoroughfare for the Delmarva Peninsula and carrying the Chesapeake Bay Bridge–Tunnel to it in Virginia.
US 13's original plan in 1926 had the route serve no further south than the Delmarva Peninsula. However, it has been extended many times, connecting to the mainland via ferry service and eventually reaching North Carolina. This link across the mouth of the Chesapeake Bay became fixed in 1964 with a bridge–tunnel. The entire route on the Delmarva Peninsula, except for a few sections in Accomack County, Virginia, has been dualized fully with four lanes, and further upgrades continue, such as a freeway section around the east side of Salisbury, Maryland.
U.S. Route 2 or U.S. Highway 2 (US 2) is an east–west United States Numbered Highway spanning 2,571 miles (4,138 km) across the northern continental United States. US 2 consists of two segments on either side of a portion of Canada. Unlike some routes, which are disconnected into segments because of encroaching Interstate Highways, the two portions of US 2 were designed to be separate in the original 1926 highway plan.
The western segment of US 2 begins at an interchange with Interstate 5 (I-5) and State Route 529 (Maple Street) in Everett, Washington, and ends at I-75 in St. Ignace, Michigan. The eastern segment of US 2 begins at US 11 in Rouses Point, New York, and ends at I-95 in Houlton, Maine.
