US 11(N-S)/US 15(N-S) Duplex

US 11 and US 15 join for a long 58-mile, same-way duplex along the west side of the Susquehanna River from Shamokin Dam to Camp Hill through Snyder, Juniata, Perry, and Cumberland Counties.

This page covers the ends of the duplex. Several pages of photos of this duplex cover the route between the ends; see the US 11 or US 15 Corridor pages.

Northbound US 11/US 15 approaching the northern split. The two routes have been joined for 58 miles from Camp Hill to here. The right lane is the offramp from PA 61 at its interchange and terminus.

Overhead signs showing the split. US 15 continues as a four-lane highway, alternating divided and undivided to the White Deer bypass.

That offramp from PA 61 becomes the right turning lane to US 11. Above the yellow cautionary sign is a distant mountain from across the Susquehanna River. Not only do US 11 and US 15 split here, but just north of here, the two branches of the Susquehannna River merge.

The first northbound US 11 shield with the Susquehanna River along the route's side. Across the river is Sunbury and the PA 61/PA 147 duplex.

Mileage signs at the beginning of the lengthy duplex. US 11/US 15 extends slightly past Harrisburg, about an hour's drive to the south.

Signs and traffic signals at the northern split, still in the view of US 11 southbound.

If you make a right turn, you will see US 15's first reassurance shield preceded by an I-80 trailblazer.

On US 15 south, US 11 enters from the left. The river is just beyond the closer trees.

First reassurance shields southbound at the rural north end of US 11/US 15. The PA 61 overpass is just around the bend.

 

Timothy Reichard 8/19/02

58 miles to the south, US 11/US 15 meets the interchange with the PA 581 Capitol Beltway in Camp Hill. US 11 exits onto the Beltway as US 11/PA 581 while US 15 continues south on its own freeway. The first exit of the cloverleaf interchange is to US 11/PA 581.

 

Timothy Reichard 8/19/02

Now on US 15 alone, the exit to PA 581 east is next.

 

Timothy Reichard 7/24/02

Exit 5 of PA 581 is the southern split of US 11/US 15 and the eastern split of US 11/PA 581. US 11 leaves PA 581 and joins US 15 in Camp Hill. This interchange is almost 60 miles from the northern split of US 11/US 15.

 

Timothy Reichard 7/24/02

US 15 south heads to Gettysburg, while US 11/US 15 northbound start a 50-mile duplex to Shamokin Dam along the west shore of the Susquehanna River.

 

Timothy Reichard 8/19/02

The US 11/PA 581 eastern split. The cloverleaf interchange has tightly curved ramps and is quite congested at rush hour. PennDOT is studying this intersection for a future upgrade to ease congestion and increase safety. PA 581 ends at I-83 at the next exit.

The view of the southern split as seen from US 15 northbound. US 11 leaves PA 581 to join US 11/US 15, which begins straight ahead.

US 11 merges onto US 15 here from the right. The south end of the duplex begins here.

 

 

Future Construction

The US 11/US 15 duplex will soon be shortened when the planned US 15/PA 147 Shamokin Dam Bypass is completed (2008?). US 11 will remain routed through Shamokin Dam, but duplexed with a new Business US 15 from the north stub end of the Selinsgrove Bypass (where current US 11/US 15 and US 522 meet) to the current US 11/US 15 split, which will be a US 11/Business US 15 split. US 15 will leave US 11 at the north stub end of the Selinsgrove bypass and continue on a new alignment that will extend the bypass around Hummels Wharf and Shamokin Dam. West of Shamokin Dam, PA 147 will join US 15 northward to a new Winfield interchange, from which US 15 will continue northward on its current route.
