Mason Street

Planning, Structural, Survey, Transportation | Wisconsin | Back


The Mason Street project was part of the I-41/STH 29 expansion project. It included reconstruction of 0.583 miles of Mason Street (WIS 54) and 0.608 miles of I-41. Highlights include three bridges, a box culvert, 11 retaining walls, 10 sign structures, three roundabouts, a stormwater pond, multi-modal trails, and context-sensitive solutions (CSS). The CSS elements included stained and textured structures, Native American murals on retaining walls, decorative crosswalks, lighting, and extensive landscaping throughout the project.

This stretch of Mason Street was an urban commercial corridor and one of two primary east-west arterials providing access to Lambeau Field, the Green Bay Packers’ stadium. Mason Street could be closed for no more than six months and needed to be completed prior to the start of the professional football season.


These constraints made it necessary to construct the roadway from winter through early spring. Four lanes of traffic were maintained on I-41 throughout the project. Design and construction schedule modifications were made to accommodate high groundwater on I-41. To maximize schedule and funding, the project let was advanced five months. This fast-tracking of the let required extensive utility coordination to ensure no facility conflicts during construction.
