Lexington Parkway Realignment

Lexington Parkway is an important roadway within Ramsey County carrying 7,000 vehicles daily. Ramsey County, Saint Paul, and MnDOT identified the need to remove Lexington Parkway from the five-way intersection with Montreal Avenue and West 7th Street to improve vehicle and pedestrian mobility, selecting TKDA to work on the design, public engagement, and construction administration. TKDA’s integrated team of engineers, planners, landscape architects, and surveyors worked with the County to improve the safety of vehicular and pedestrian traffic, replace aging infrastructure, and improve regional connectivity and multi-modal opportunities.

This project successfully combined a unique blend of innovative design and engineering techniques while focusing on community and stakeholder engagement to improve vehicular and pedestrian mobility and replace aging infrastructure. Several innovative design elements were created to deliver this project including the tree trench and reinforced sidewalk slab. Other specialized items included pipe-bursting watermain, dedicated bike lanes, contaminated soil removal, bedrock removal, street lighting, signal interconnect, guardrail to protect railroad abutment, vertical shaft connections to deep trunk stormwater pipe, and a mini-roundabout. This project marks the first roundabout in the City of Saint Paul.
