Our engineers played a key role on the design-build team for the federally funded rehabilitation of this historic 1,700-foot-long bridge—a combination concrete girder and steel truss movable structure spanning the Thea Foss Waterway and the BNSF mainline. The project involved extensive structural repairs, including the replacement of the truss bottom chord, gusset plates, steel stringers, […]
Engaged by ODOT, our team developed scopes of service for local bridge projects, delivering cost estimates, engineering data, and assessments of right-of-way and environmental impacts. Serving ODOT Regions 1 and 5, we provided precise documentation and adhered to ODOT’s General Expectations to ensure responsible, long-term value for public funds.
As Engineer of Record, our team oversees major wall structures and provides structural engineering for new street connections and upgrades along I-5 from I-405 to the Morrison Bridge, including the Broadway/Weidler Interchange. Scope includes seismic evaluations for nine bridges and Phase 1 seismic retrofits to enhance infrastructure resilience.
Provided structural engineering services for bridge deck replacement, expansion joint installation, and utility coordination on a historic bridge connecting Dallesport, WA, and The Dalles, OR. Project utilized Accelerated Bridge Construction (ABC) to minimize closures and impact.
Following flood damage near Elbe, Washington, our team assessed and designed the replacement of the Nisqually River Trestle on Tacoma Rail’s Mountain Division Line. We evaluated multiple bridge alternatives, selecting a two-span steel plate girder bridge for optimal performance, cost-efficiency, and environmental compliance, ensuring a resilient and sustainable rail connection.
Our team served as Engineer of Record for LA Metro’s Westside Purple Line Extension, designing Century City/Constellation Station and reviewing plans for Wilshire/Rodeo Station. The project demanded advanced soil-structure interaction, 3D modeling, and excavation support to ensure stability beneath densely developed areas along Wilshire Boulevard, factoring in seismic resilience and loading impacts from nearby high-rise buildings in this urban infrastructure initiative.
Bowman was engaged by the MBTA for a four-year, $7M contract to plan, design and construct a wide range of bus system infrastructure projects to further upgrade and enhance bus system accessibility, safety, state of good repair, service reliability, travel times, and system wide expansion.
The overarching goal of the North Station to Seaport Bus Link project is to improve transit connectivity across the Downtown core of the City of Boston to meet current and future transit demands.
As part of several distinct projects along the Crystal Drive corridor, Bowman prepared designs for the construction of streetscape improvements including multi-modal transit accommodations with protected bicycle lanes, urban landscaping, green stormwater infrastructure, street lights and infrastructure improvements.
Our role included subsurface utility engineering quality levels B, C and D along approximately seven miles of I-25 right-of-way from the Dona Ana Interchange south to Lohman Avenue, with an additional seven miles of densely populated utility corridors beneath several arterial roadways and interchanges.
