Trumbull Corporation is a Pittsburgh heavy highway and heavy civil contractor and an ENR Top 100 firm, operating from offices in Pittsburgh, Harrisburg and Horsham with more than 300 field and office staff. It builds bridges, highways, sitework and energy infrastructure across Pennsylvania and neighbouring states, and it is part of the PJ Dick, Trumbull and Lindy Paving family under PJTC Holdings. Named work includes the Charleroi Locks and Dam, the Central Susquehanna Valley Transportation bridge, the Cleveland Innerbelt, Pittsburgh’s North Shore Connector and the Intercounty Connector in Maryland. In December 2024 Trumbull and Brayman Construction won the $769.9 million base contract to build the new 110-by-600-foot river chamber at Montgomery Locks and Dam on the Ohio River, the first component of the Corps of Engineers Upper Ohio Navigation Project.
More than 200 bridges, over 100 miles of highway and millions of cubic feet of excavation sit behind Trumbull’s name. The company was founded in 1955, and today runs roughly 400 full-time people covering every discipline a heavy civil job needs: engineers, estimators, project managers, safety managers, schedulers, surveyors, foremen and superintendents, laborers, equipment operators and mechanics.
Owned equipment is a large part of how the firm competes. Trumbull runs 300-ton cranes, pile hammers, DM-45 drills, and scraper and truck spreads, and works from 3D models with GPS machine-control equipment and drones, which lets crews perform mass excavation at high production rates. On the bridge side the company builds arch, tied arch, cantilever, cable-stayed, truss, delta-frame and beam structures, and takes work through design-bid-build, design-build, general contracting and public-private partnership arrangements. Named work includes the Scudder Falls Bridge replacement spanning Pennsylvania and New Jersey, the 200-foot-high Shenandoah River Bridge in West Virginia, the Woodrow Wilson Bridge at Fort Washington, Maryland, the Southern Beltway for the Pennsylvania Turnpike, and 3.75 miles of new US 220 highway in Maryland.
A separate energy group prepares sites for gas, electric, water, power and industrial infrastructure and has delivered more than 450 projects for 33 clients in the oil and gas industry. Its scope covers pad sites and impoundments, cement stabilization, erosion control, drainage, grading, and MSE, pile and lagging retaining walls. Working alongside sister company PJ Dick Industrial, the group moved nine million cubic yards of dirt and handled sitework for the 400-acre Shell ethylene cracker plant at Monaca, Pennsylvania. Trumbull holds an A rating with ISNetworld and is a registered PECS user.
Quality control is built on Army Corps of Engineers core principles, with a project-specific plan written before work starts and a quality control manager assigned to run sampling, material testing, and field and lab work with state- and industry-certified inspectors. Safety runs under an award-winning internal program the company calls My Safety. Trumbull routinely bids and builds in Pennsylvania, West Virginia, Ohio, Maryland, New Jersey, Delaware, Virginia, Kentucky and Washington, D.C., and has been recognized by the International Partnering Institute, Pennsylvania Constructors and the American Council of Engineering Companies.
