Bridge Construction & Maintenance in Central Pennsylvania
JDI Site Solutions builds and maintains vehicle, pedestrian, and farm crossings for townships, developers, and property owners across Central Pennsylvania. We work from the engineer’s sealed plan through construction, handle the permitting coordination that comes with building over water, and return for the repair work a structure needs as it ages.
Bridge Construction for Public and Private Crossings
A bridge project in Pennsylvania starts with the water underneath it. Any structure that changes the course, current, or cross section of a watercourse or floodway falls under Chapter 105 of the Dam Safety and Encroachments Act, and most crossings qualify under one of the DEP general permits provided they stay inside the criteria. Structures longer than 100 feet upstream to downstream, or anything in exceptional value waters, moves to a joint permit instead. We build the abutments, foundations, decks, superstructure, approaches, and railings the approved drawings call for, and coordinate the permit work alongside your engineer.
The crossings we build range from township and borough road structures to pedestrian and trail bridges, agricultural crossings for working farms, and private access bridges on larger properties. Our crews come out of a site work operation covering excavation, culverts, and waterway restoration, so the stream work, bank stabilization, and earthwork around a structure are handled by the same people rather than split across trades. We carry PA Contractors License #PA178908 and $10 million in insurance coverage, with over 30 years of combined experience behind the work.

Repair and Maintenance on Structures Already in Service
Most bridge spending is not new construction. It is deck deterioration, spalling concrete, corroded steel, scoured abutments, failed joints, clogged drainage, and railings that no longer meet the standard they were built to. Left alone, each of those turns a maintenance line item into a replacement project. We handle condition assessment, concrete and steel repair, deck work, railing replacement, drainage clearing, protective coating, and abutment and scour repair on structures that are still carrying traffic.
Repair work on an existing serviceable structure generally moves through GP-11, which goes directly to DEP rather than through the conservation district, and that difference matters to a schedule. We plan the work around it, along with traffic control, detour requirements, and the in-stream work windows that apply to the waterway. For owners carrying several structures, we assess them together and sequence the work by condition so the budget goes where it is doing the most good.
Built to the Sealed Plan
Foundations, spans, decks, and railings constructed to the elevations and specifications on the approved drawings.
Permitting Coordinated
Chapter 105 general permits, E&S approval, and PNDI clearance handled alongside your engineer and the reviewing agency.
Repair and Maintenance
Condition assessment, concrete and steel repair, deck and railing work on structures still in service.
Frequently Asked Questions
Permits, whether a structure can be repaired instead of replaced, and what drives the number on a quote account for most of what township supervisors and property owners ask before a bridge project starts. Here is where we usually begin.
What types of bridges do you build?
Vehicle crossings for township and private roads, pedestrian and trail bridges, agricultural crossings for working farms, and small to medium span structures on commercial and private property. The span, the load the structure has to carry, and the waterway underneath set what is possible on any given site.
What permits does a bridge project need in Pennsylvania?
Work over a regulated waterway falls under DEP Chapter 105. Many crossings fit a general permit, while longer structures and exceptional value waters require a joint permit. An E&S plan approved by the county conservation district is required for Chapter 105 work, other than GP-11, which goes straight to DEP. PennDOT enters the picture when a structure carries or ties into a state route.
Do you build from our engineer's design?
Yes. Bridge design in Pennsylvania requires a licensed professional engineer, and we construct from plans your engineer has prepared and sealed. Our role is building to those drawings, coordinating permits, and flagging conditions in the field that differ from what was assumed on paper before they become a problem.
Can an existing bridge be repaired instead of replaced?
Often, yes. It depends on the condition of the foundations and primary structural members rather than how rough the surface looks. We assess what is there, identify what can be repaired and what cannot, and give you a straight comparison so the decision between repair and replacement is made on the actual condition rather than a guess.
How long does a bridge project take?
Span, foundation conditions, and permitting drive the schedule far more than the build itself. Permit review can run months before anyone mobilizes, and in-stream work windows limit when construction can happen. We give you a timeline that accounts for the approval stage rather than one that starts on the day the crew arrives.
What determines the cost of a bridge project?
Span length, required load rating, foundation and soil conditions, whether the waterway is regulated and at what level, traffic control or detour needs, and whether the work is repair or full replacement. Private driveway and farm crossings sit at the lower end of that range. We quote after a site assessment and a look at the plans rather than off a rough description.
