Wauwatosa Watertown Plank Road Bridge Rehabilitations

« Return to Project Search

The Wisconsin Department of Transportation retained Ayres to provide preliminary and final roadway and structure plans to replace the concrete deck and roadway approaches on two adjacent structures on Watertown Plank Road west of STH 100 (Mayfair Road) in Wauwatosa. The bridges cross two railroads, Underwood Creek, and the Milwaukee County Oak Leaf Trail.

The bridge decks were replaced due to deterioration and widened to provide for on-road bicycle accommodations. Work was staged to maintain traffic at all times by the use of median crossovers.

Extensive public involvement was required for this project because of the confined work zone; number of businesses, including large office complexes, within the project area; proximity of this project to the Zoo Interchange reconstruction; and the presence of the police department and Wauwatosa Fire Station #53 adjacent to the project limits. In addition to a local official and public involvement meetings, individual meetings were held with emergency services and businesses in the area to get their input for the construction staging.

Services included survey; agency coordination; railroad coordination; the environmental document; public involvement and meetings; the Design Study Report; preliminary and final roadway design; traffic control staging plans and signing; preliminary and final structure plans; and final plans, specifications, and estimates (PS&E).

A contractor constructability workshop was coordinated and held through the Wisconsin Transportation Builders Association. This was an interactive workshop between design staff and contractors to address items such as project access, construction staging, and construction schedule. The goal was to work jointly with contractors to provide a PS&E package for a project with various unique challenges that could be bid tightly and within budget.
