Why is this project being done?

• Stormwater runoff quality to be improved by constructing an infiltration trench to send water into the aquifer instead of a directly to the Huron River which gives soil the opportunity to filter out pollutants.
• Consolidation of two aging water mains maintained by the City of Ann Arbor and the University of Michigan into one.
• Protected bicycle lanes.
• Two raised mid-block crosswalks to enhance safety for people crossing the road.
• A northbound transit queue jump lane to improve bus headway times along the corridor.
• A transit signal at the intersection of State Street and East William to allow buses to get ahead of other vehicles.
• Enhanced bus stops for northbound and southbound riders.
• On-street parking will be removed to make space for the transit and bicycle improvements. The city is reviewing adjacent locations for on-street parking.
