Connecting communities through transportation.

As our first major bridge project, this concrete and steel bridge over the Massawippi River, at the south limit of Lennoxville, Quebec, established the foundation for our continuously growing bridge practice.

Spanning 550 feet over the Saint-François River in Sherbrooke, this new bridge stood as one of the longest reinforced concrete bridges in Quebec. Use of this material was an innovation in Canada at the time and a testament to the power of progress through design.

To address significant development within Sherbrooke, Quebec, we proposed a new steel and reinforced concrete structure over the Magog River. The bridge opened in 1954.

Acting as the Owner’s Engineer, we oversaw successful completion of a new railway for the Port-Cartier Mining Company, now ArcelorMittal Mines Canada. Spanning 500 km, this freight railway in Quebec connected two mining cities with a vital port city. (stock illustration)

Built in 1965 across the St. John River in New Brunswick, the 600m bridge was part of the former Trans-Canada Highway network. Design brought an important regional connector still utilized today. (photo, 2015)

As the only crossing of the St. John River between Woodstock and the Mactaquac Hydro Dam in New Brunswick, this 380m bridge boasts a main span of 217m. The cable-stayed suspension design adds to the beauty of the surrounding landscape. (photo taken after 1967)

Built as part of the Trans-Canada Highway system, this cable-stayed bridge crosses the St. John River at Longs Creek in New Brunswick. Designed as a striking landmark, with a center span of 217m between the two towers, the structure complements the natural beauty of the surrounding landscape. (modern day photo)

In the 1980s, funding was approved for a new rail line for southwestern Chicago. EXP was a key member of the team responsible for planning the Southwest Transit Project, known as the CTA Orange Line. The team planned station locations across two potential routes. The new line officially opened in 1993. (photo, 2006)

At its opening, the iconic new King Khalid International Airport in Riyadh, Saudi Arabia was one of the largest airports in the world. We provided geotechnical consulting for this significant global aviation project. (modern day photo)

Design of the new Autoroute 55 (Highway 55) in Sherbrooke, Quebec marked an important milestone in the growth of the region. Work began in 1981 and the first section linking Highway 55 to Route 216 was inaugurated in 1985.

Design of this iconic new structure offers spectacular views of Coaticook Gorge and the Coaticook River in Quebec. At the time of construction it was the longest suspended pedestrian bridge in the world. To this day, it is still one of the longest suspended pedestrian bridges in North America. (photo, 2021)

The 2.71-mile ATS is a driverless, fully-automated people mover operating 24/7, 365 days per year. EXP designed the entire structure and terminal connectors in a complex, restricted operational environment. This notable project was the recipient of multiple industry awards.

Design of this unique bascule bridge in Sheboygan, Wisconsin, redefined movable bridge design with new innovations. With no counterweight and a very simple and unusual structural framing system, the bridge also featured state-of-the-art, computer-controlled hydraulic bridge drive and control systems.

Design of this five-span highway structure spans between Lemeque and Miscou Islands near Caraquet in New Brunswick. Three main spans are steel plate girders of 110m, 160m and 110m.

Architectural and engineering services for the award-winning renovation of the Lake/Wells Subway Station in downtown Chicago. The fluid form of the canopies is derived from existing turn-of-the-century examples on Michigan Avenue, reinterpreted with a modernist sensibility.

Design of this multi-use bridge in Sherbrooke, Quebec, brought one the world’s first uses of reactive powder concrete (RPC), an ultra-high strength concrete. (photo, 2010)

This award-winning project relocated the northbound lanes of Lake Shore Drive away from the edges of Chicago’s lakefront - creating the new Museum Campus and Burnham Park. The resulting development is one of the most important civic projects completed on Chicago’s lakefront in the second half of the 20th Century.

The light-filled design transformed this 700 foot-long concourse, creating a new presence within the terminal at Chicago O’Hare International Airport.

The Old Plank Road Trail (OPRT) Bridge carries a bicycle path and pedestrian walkway along an old, abandoned railway alignment across US Route 45 in Frankfort, Illinois. With a unique and visually striking design, the pedestrian bridge's defining structural feature is an 82-foot tall A-frame pylon with bestriding the highway at right angles.

Design for reconstruction of the Western/O’Hare Station replaced the existing station and platforms. The original station was built in 1895 and renovated in 1935. The new station was designed as a background building to the restored, historically significant portions of the existing station.

Structural and geotechnical engineering for one of the largest single-structure garages in North America. At 4,800,000 SF, it accommodated 9,000 vehicles over eight stories with 2,000 tons of tendons.

Dubbed by the local press as the "Jewel of Indianapolis," this new tower was designed as a landmark - visible from miles around and symbolizing the airport as a gateway to the city of Indianapolis.

Enhancements to and renovations of the public areas in Concourses A and C brightened and heightened the sense of space. Design incorporated new finishes, lighting, wayfinding and public art.

Soils and materials engineering, quality assurance services for construction of a 425km stretch of this 6-lane highway - one of the longest highways in the world.

Designer of record for the new Juneau Avenue Vertical Lift Bridge and rehabilitation of the Wisconsin Avenue Vertical Lift Bridge in downtown Milwaukee, Wisconsin.

Design of a new 4-span steel girder bridge with composite deck – spanning approximately 230 meters over the Saint John River and connecting the communities of Clair, New Brunswick, and Fort Kent, Maine. The intersection within Fort Kent’s Main Street marks the beginning of the 2,369-mile-long US Route 1, the longest north-south road in the US.

Geotechnical and pavement design for a new 4-lane highway and road upgrades to the existing TransCanada Highway - the largest transportation infrastructure project in Saskatchewan’s history.

Design lead as part of the WestEnd Connectors DBF team. The ECWE project involves twin bored tunnels and associated structures and shafts required for a new subway extension along Eglinton Ave W in Toronto, Ontario. The extension spans 9.2km with 6 new stops and a terminal.

Transformation of this 22.5-mile corridor of I-66 has enhanced multimodal use and reliability with new express lanes, new transit routes, interchange improvements and bike/pedestrian trails. EXP provided bridge, structure and pavement design as part of this P3 project between Virginia DOT, the Department of Rail + Public Transportation and private partner, I-66 Express Mobility Partners.
