Make Our Transportation System Equitable, Accessible and Clean.

Most recent update:

A 'Better Beltline' Corridor does not include additional lanes

Wisconsin Department of Transportation (WISDOT) is studying a possible expansion of the number of lanes on the beltline, and their most recent Planning and Environmental Linkages (PEL) study update includes the possible addition of a general purpose lane as well as an extension of the flex lane from USH 18/151 to Parmenter St.

While the current study includes some exciting proposals including improved local road crossings, bike and pedestrian connections, park and ride options and transit priority improvements, the inclusion of an additional travel lane is disappointing.

Why it Matters

Multi-modal transportation systems are not only good for the climate -- they're good for people! It connects us to opportunities and helps public health. Show support for walking, biking and public transit!

Wisconsinites deserve an effective, convenient and clean transportation system that connects everyone to the places they want to go.

By supporting a range of transportation options (like walking, biking and transit), better connectivity across communities, and more livable communities, we envision a healthier, happier Wisconsin for all who live here.
