I-83(N-S)/US 322(W-E) Duplex
Interstate 83 and US Route 322 join for 4 miles on the east side of Harrisburg in Dauphin County.
Douglas Kerr 9/27/03The I-83/US 322 duplex is full of interest. We begin at the southern split, which is one of the more complicated interchanges in the state, the Eisenhower Interchange. Here I-83 and US 322 split, I-283 begins, and US 322 runs between two sub-interchanges in such a way such that US 322 east shares a roadway with both I-83 north and south at different places. This is the north end of I-283.
There is also a peculiarity on these overhead signs. Pennsylvania right-justifies exit tabs for exits to the right, and left-justifies exits from the left lane. Here there is a rare third exit as I-283 becomes I-83/US 322, and the exit tab is center-justified.

Here is I-83 northbound approaching the interchange.
Timothy Reichard 8/19/02On I-83 northbound, first I-283 exits to the south.
Timothy Reichard 8/19/02The next observation is unusual. There is a lane to the right that is separated from the rest of the mainline. It's actually US 322 east along I-83 north, just before I-83 north and US 322 west join—more on this later.
Timothy Reichard 8/19/02Next, I-83 splits off on one lane to the north while the mainline soon becomes US 322.
Timothy Reichard 8/19/02I-83 curves more than 90 degrees to the north. US 322 west soon joins.
Timothy Reichard 8/19/02Before continuing north, we return to the southern split as seen on US 322 west. Here ramps to I-283 and I-83/US 322 leave at the same place. The curvy bridge carries I-83.
Timothy Reichard 8/19/02A closer view of the interchange.
Timothy Reichard 8/19/02Another view of the stack interchange. The curvy bridges carry I-83, and the straight bridge carries I-283. The sign between the mainline and ramp read NORTH I-83 TO I-81.
Timothy Reichard 8/19/02US 322 does not directly join I-83. First it follows Eisenhower Boulevard with a partial cloverleaf interchange with Derry Street. Then the eastbound and westbound lanes of US 322 separate to connect to I-83 on each side of the mainline, which is hidden by the trees.
Timothy Reichard 8/19/02First reassurance shields on I-83/US 322. The main function of this freeway stretch is to reach I-81, where I-83 ends.
Timothy Reichard 8/19/02I-83/US 322 meets two interchanges between the ends of the duplex. The southern interchange is for Union Deposit Road, which serves east Harrisburg.
Timothy Reichard 8/19/02A few miles to the west, US 22 and US 322 join for the long US 22/US 322 duplex. After splitting near Harrisburg, the two routes meet again here.
Timothy Reichard 8/19/02Past the US 22 interchange, I-83 will soon end at I-81, and US 322 will join I-81 for another interstate highway duplex. I-81 north goes to I-78, the main route to the Allentown area.
Timothy Reichard 8/19/02The north- and southbound lanes separate as the interchange with I-81 approaches. From here, US 322 serves little unique purpose for some 60 miles, after which it serves as the main route to State College.
Timothy Reichard 8/19/02US 322 splits to the west on I-81 south. The I-81/US 322 duplex serves the northern Harrisburg area. The barrier is part of the widening reconstruction project of I-81 from Front Street to this I-81 & I-83 interchange. All of I-81/US 322 was under construction at this time, August 2002.
Timothy Reichard 8/19/02Now we approach the northern split via I-81 south. The I-81 & I-83 interchange is not only the northern split of I-83/US 322, but also the eastern split of I-81/US 322.
Douglas Kerr 9/27/03New signs and sign gantries were erected as the I-81 reconstruction project continued into later phases. A diagrammatic guide sign was placed along I-81 north/US 322 east at the interchange with I-83.
Timothy Reichard 8/19/02Reassurance shields southbound.
Timothy Reichard 8/19/02The true I-83/US 322 southern split is at Exit 47, where technically US 322 joins/leaves the I-83 freeway.
Timothy Reichard 8/19/02US 322 splits at Exit 47. We now follow an unusual routing through the Eisenhower Interchange, which, as hinted at earlier, brings US 322 back on I-83 but in the opposite direction. Initially, US 322 joins Eisenhower Boulevard.
Timothy Reichard 8/19/02US 322 from here (Eisenhower Boulevard) east to at least PA 241 bare HERSHEY banners, as US 322 is the main route through Hershey, the Chocolate Capital of the World. This location is the interchange with Derry Street.
Timothy Reichard 8/19/02A few tenths of a mile to the south, eastbound US 322 exits onto I-83 northbound.
Timothy Reichard 8/19/02(This photo was shown above.) US 322 east leads to the separated lane at the right.
Timothy Reichard 8/19/02Once I-83 exits the mainline, that lane of US 322 east joins the mainline as a more normal freeway.
