​Market Street Bridge


As we receive comments, the website will be updated.  Please come back for new information.

The Pennsylvania Department of Transportation (PennDOT) invites the public to an online plan display regarding the Market Street Bridges, part of State Route 3012 in Dauphin County, which connects the communities of Lemoyne and Wormleysburg on the west shore of the Susquehanna River with City Island and the City of Harrisburg on the east shore. As one of the four main river crossings in the Harrisburg area, Market Street provides a key connection that must be maintained. To maintain the crossing for years to come, work must be completed to both the western and eastern bridges. 

PennDOT is currently performing preliminary engineering and environmental studies for a planned project to rehabilitate both the western and eastern bridges.
The western bridge is a 16-span adjacent concrete box beam bridge that connects Lemoyne and Wormleysburg to City Island over the west channel of the Susquehanna River. The eastern bridge is a 16-span closed spandrel arch bridge that connects City Island to the City of Harrisburg over the eastern channel of the Susquehanna River.

Both bridges currently carry state Bike Route J. Though bicyclists have access to the roadway, there is no dedicated bike lane or sharrow signs on the roadway notifying motorists to share the road. Bicyclists also use the existing sidewalks.

Sidewalks are deteriorated on the eastern bridge. In addition, metal plates for the hatches used to access the interior of the bridge are located within the existing sidewalks. Many of these hatches are not accessible for interior bridge inspection, and damaged hatches cause tripping hazards on the sidewalks. On the western bridge, sidewalk panels exhibit cracking and spalls.

The purpose of the project is to maintain safe and efficient multimodal connectivity across the Susquehanna River between Harrisburg and the West Shore communities, as well as access to City Island and its amenities. The eastern bridge is listed on the National Register of Historic Places; therefore, it is a goal of the project to maintain the historic integrity of the bridge.

The scope of work for the bridge improvements includes rehabilitation of the historic arch and replacement of the deck and sidewalks on the 16-span eastern bridge as well as construction of a new superstructure (deck and beams) on the 16-span western bridge. Currently, the eastern bridge provides four 10-foot lanes and two 5-foot 9-inch sidewalks with no shoulders on either side, while the western bridge provides four 10-foot lanes and two 4-foot 7-inch sidewalks with no shoulders on either side.  

With the proposed rehabilitation work, three options exist to improve bicycle and pedestrian accommodations.  In each option, sidewalks will be replaced with an improved, smoother surface.  The metal plate hatches will be relocated to the roadway for better access. Additional bicycle signage and pavement markings, such as sharrows, will be considered for any option chosen.

Option 1:  Maintains four 10-foot lanes for both bridges, similar to current conditions.  It improves the sidewalk surfaces on both bridges, but it maintains two 5-foot 9-inch wide sidewalks on the eastern bridge. This option does not provide additional bicycle accommodations on the eastern bridge other than smoother sidewalks. For the western bridge, two 7-foot sidewalks along with 2-foot shoulders are proposed, which will provide additional space for bicyclists.  This option would also allow the roadway to be restriped in the future for three vehicular lanes and add bike/pedestrian accommodations if warranted at a later date.

Option 2: Maintains four 10-foot lanes for both bridges, similar to current conditions. The upstream sidewalk is eliminated on both bridges in order to provide a wider downstream sidewalk (9-foot 6-inch wide on eastern bridge and 10-foot wide on western bridge).  Two shoulders (1-foot wide) are also provided on the western bridge and one 1-foot shoulder can be provided on the eastern bridge for additional space for bicyclists.  The wider sidewalk can be considered a “shared use path”, that will allow pedestrians and bicyclists to comfortably use it simultaneously.

Option 3: Reduces to three 10-foot lanes and provides a wider upstream sidewalk for pedestrians (7-foot 6-inch wide on eastern bridge, 6-foot wide on western bridge), a wider downstream sidewalk for shared use (10-foot wide on both bridges), and 2-foot shoulders between vehicles lanes and raised sidewalks which provides additional space for bicyclists.

During construction, traffic could be maintained by several different options that include:
  • full detour of vehicular traffic on the western bridge which may allow shorter construction durations
  • detouring westbound traffic while maintaining one lane eastbound between the west and east shores. 
  • Maintaining one lane in both the eastbound and westbound directions during construction which could complicate the construction and lengthen construction durations. 
Vehicle Access to City Island – With all detour options, vehicular access to City Island will be maintained for the duration of construction.

Bicycle and Pedestrian Access – With all detour options, bicyclist’s and pedestrians’ access across both the western and eastern bridges will be maintained for the duration of construction.

Boater Access Under the Bridge – Construction of the bridges will require half-width causeways in each channel for contractor access (half of the eastern and western channels will always be open). An Aids to Navigation plan will be developed in coordination with the PA Fish and Boat Commission. Boater access will be maintained in areas not occupied by causeways.  Access will be maintained in each channel of the river for the duration of construction.

The project is currently in the preliminary design phase, and construction is anticipated to begin in 2024 subject to all approvals, environmental clearances, and funding availability. Currently, $63.8 Million is estimated for construction.

A digital version of the information will be available for public comment until 11:59 PM Friday, February 11, 2022. An in-person open house will be held on January 18, 2022, at the Wormelysburg Borough Office, Knisley Hall from 10 am - 12 pm and 6 - 8 pm.
