what we do

Roadway and Highway Design

Designing infrastructure to safely and efficiently move people and goods

Providing safe and efficient roads and highways is more challenging today due to limited funding and increasingly complex regulatory processes. Parametrix works with clients to develop solutions that are cost effective and minimize disruption to users and the environment. We incorporate LID, green streets, and complete streets principles to create appealing, safe, and sustainable transportation right-of-ways.

Pacific Avenue Improvements 
Bremerton, Washington
Client: City of Bremerton

Pacific Avenue is the City of Bremerton’s primary downtown corridor. This improvement project converted an existing 5-block stretch of deteriorated corridor into a state-of-the art sustainable, green street, and complete street that encourages revitalization and connects the City’s primary waterfront parks. Parametrix provided design and permitting services for this federally funded project including stakeholder coordination, alternative design development, sidewalk and streetscape design, roadway design, and full PS&E. The project included creation of an urban trail, a full LID retrofit consisting of permeable pavement and rain gardens, as well as LED lighting and electric car charging stations. Underground utility conversion was a significant element of the project and required extensive coordination with multiple utilities. An accelerated project schedule and the proximity of several historic structures required the team to address NEPA and section 106 permitting early in the process. The fast-track 4-month design was completed on time and on budget.
