Wagman Inc. (@wagmaninc) has completed the I-270 at Watkins Mill Road Interchange project (top) in Gaithersburg, Maryland, six months ahead of schedule. The road is now open to traffic.

The $90 million project for the Maryland State Highway Administration required a new interchange on I-270, consisting of 14 structures, including a five-span bridge over I-270 and a two-span bridge along an off-ramp. In addition to the main structures, the project featured two box culverts, a 72 inch storm drain, numerous cast-in-pace and MSE retaining walls, and the complete reconstruction of a tributary of Seneca Creek.

Wagman is a multi-faceted construction firm with major operations in heavy civil, general construction, and geotechnical construction services. It is based in York, Pennsylvania.


WSP USA (@wspusa) was selected by the Texas Department of Transportation (TxDOT) to provide design services for the Interstate 30 (I-30) Dallas Canyon Interchange project and the planning of highway improvements in the Odessa District’s Permian Basin. The firm will take the lead role in providing TxDOT with the design and preparation of plans, specifications and estimates, and related documents for improvements to the depressed I-30 roadway known as the “Canyon,” extending from the Interstate 35E interchange to the Interstate 45/Interstate 345 interchange.

The 1.5-mile-long, $369 million project includes the traffic control concepts to accommodate the 244,800 average daily vehicles and the design of multiple deck parks to re-invigorate the area around the Dallas Convention Center and the neighborhood known as The Cedars. This project will connect to WSP’s previous work on several Dallas mega projects in the area, including the Dallas Horseshoe DB, Texas High Speed Rail and The Southern Gateway DB, as well as the Dallas I-345 Feasibility/PS&E Study.

WSP USA is one of the world’s leading engineering and professional services firms, with more than 9,500 employees in 150 offices across the nation.


Modjeski and Masters (@ModjeskiMasters) has begun work for the final design of the vertical lift span on the I Street Bridge in Sacramento, California. The project, owned by the City of Sacramento, is being built upstream of the existing I Street Bridge to enhance accessibility across the Sacramento River.

Modjeski and Masters is responsible for the structural, mechanical and electrical design of the new vertical lift bridge. The firm is working with Mark Thomas as the prime consultant and TY Lin as the architect.

The $220 million project  is a vertical lift  network tied arch bridge, and will be the first of its kind in the world. It will accommodate three highway traffic lanes, bicycle lanes, sidewalks and a future streetcar. Modjeski and Masters will incorporate lightweight materials into the movable span design to ensure structural durability and aesthetic appeal. 

Modjeski and Masters is a nationwide leader in the design, inspection and rehabilitation of all bridge types, including long-span and movable structures. The firm is based in Mechanicsburg, Pennsylvania.
