The John Harris Bridge , also South Bridge , is a seven-lane road bridge over the Susquehanna River between Harrisburg and Lemoyne in the state of Pennsylvania in the USA . It leads the Interstate Highway 83 and is with the George N. Wade Memorial Bridge located further upstream part of the Capital Beltway , a ring road around the metropolitan area of Harrisburg. The bridge is used by an average of 96,000 vehicles daily and is operated by the Pennsylvania Department of Transportation . The bridge is named after the founder and namesake of the city of Harrisburg John Harris, Sr. (1673-1748).
The one kilometer long girder bridge was built in the late 1950s as part of the expressway connection between Harrisburg and Baltimore , which became part of the newly emerging network of interstate highways . At the time of inauguration on January 22, 1960, it had four lanes and was expanded to six by 1982. The shoulder on the downstream side was then converted into another lane in 2015 towards Harrisburg, which becomes the exit onto Second Street at the end of the bridge .
Today's main bridge consists of two parallel girder bridges made of solid wall girders that rest on 18 river pillars and form 19 spans between 43.2 m and 51.8 m. This is followed by the access roads from a large number of other girder bridges. The original bridge had two 7.9 m wide carriageways for two lanes each . By 1982 the river pillars on the downstream side were extended, the second bridge girders installed in the same design and connected to the old ones. This resulted in two 15.9 m wide lanes, which are now used for three lanes to the south and four to the north.
