West Walnut Street
GRAEF performed design services for the reconstruction of W. Walnut in the City of Milwaukee as part of WisDOT’s Local Road program. The fully developed 4-lane divided thoroughfare was surveyed to obtain detailed topographic features within the project limits. The proposed improvements included reducing the roadway to a 2-lane divided section with parking between N. 20th Street and N. 14th Street and maintaining a 4-lane divided roadway section between N. 14th Street and the eastern project limit.
GRAEF developed multiple bicycle and pedestrian enhancements as part of the project design to improve safety and accessibility. The new bike lanes on Walnut Street were designed as off-street one-way separated bike facilities which are expected to increase safety and comfort for bicyclists. The narrower vehicular roadway section is also anticipated to reduce motor vehicle speeds, reduce reckless driving, leading to fewer fatal/ serious crashes. All pedestrian curb ramps were reconstructed to current ADA standards. Raised “tabletop” pedestrian crossings were designed at all non-signalized side roads, and bump outs were also incorporated into the design to deter motorists from using the parking lane as a through lane and to shorten the distance of pedestrian crossings to enhance overall safety in the project corridor.
The project team developed street lighting plans and coordinated with the City of Milwaukee traffic signal staff to replace the signals within the project corridor. Other improvements included the replacement of storm sewer laterals and inlets, pavement marking, and roadway signing.
The project started construction in 2023 and will be substantially complete in spring of 2024.
