Minnehaha Avenue (County Road 48)

The Hennepin County Transportation Department in partnership with the City of Minneapolis is reconstructing Minnehaha Avenue from 46th Street South to Lake Street.

Improvements to Minnehaha Avenue are needed to address the deteriorating pavement, utility and drainage concerns, non-motorized accommodations and storm water quality conditions. The county seeks to design Minnehaha Avenue to be safer, more livable, and welcoming to all users, while balancing potential impacts to residents and businesses along the corridor.

Detours and closures

Minnehaha Avenue is now open to all traffic.

Major construction activities on Minnehaha Avenue have wrapped up for 2015, and the entire project area is now open to all through traffic.

2016 closures and detours

Minnehaha Avenue is scheduled to be closed to through traffic and reconstructed in two main stages in 2016:

  • April-August: 38th to 34th Street
  • August-November: 34th to Lake Street

Detour maps

Local traffic

Local traffic will be able to use fully paved streets and walkways on all areas except the four blocks under construction. Access to businesses and residences will remain available in the four block segment under construction, though surfaces may not be paved or smooth at all times.

Crossing Minnehaha Avenue

Travelers will be able to cross Minnehaha Avenue at intersections not closed for reconstruction during construction. With the exception of Lake Street, intersections will be fully closed for approximately ten days to allow for construction in and/or around the intersection. Travelers may cross at other locations during these intersection closures.

Construction updates

​Major construction on Minnehaha Avenue has concluded this year. Thank you for your patience and cooperation during the 2015 construction season. Please check back in spring 2016 for updates on the final season of work between 38th Street and Lake Street.

Project background

What design concept is the county recommending?

The county initially studied design concepts for buffered bike lanes, one-way cycle tracks, and two-way cycle tracks on Minnehaha Avenue. County staff is recommending the buffered bike lane option because it better addresses safety at intersections for pedestrians, bicyclists and vehicles and will have less of an impact on parking and trees. Minneapolis City Council approved the recommended layout on December 13, 2013.

Public involvement

Public meetings were held in 2013 to provide information about design concepts and gain public input. Hennepin County presented the recommended layout to Minneapolis City Council in December 2013 and received preliminary layout approval.

Thank you to all who have attended meetings and provided your thoughts and ideas to date.

Project highlights

  • Two 11-foot lanes of traffic
  • Dedicated left turn lanes on Minnehaha Avenue at 31st Street, 32nd street, 38th Street, 46th Street
  • A southbound right turn lane on Minnehaha Avenue at 42nd Street
  • Realignment of intersections to create 90 degree angles at 27th Avenue and 31st Avenue, 32nd Street and 33rd Street, and 36th Avenue and 37th Avenue
  • Improved pedestrian facilities (shortened crossings at intersections, improving bus stops and ramp curbs to make them fully accessible)
  • Enhanced dedicated bicycle lanes (including a stipend buffer zone and concrete pavement treatment)
  • Storm water system improvements 

Utility improvements

CenterPoint Energy plans to improve the gas mains in this corridor and will be beginning their work by early April 2015. This gas main replacement work is being completed at the same time as the reconstruction of Minnehaha Avenue. Work may extend outside the four block closure area, but traffic impacts should remain the same. Visit Centerpoint Energy's project website for more information.

Residents may improve their sewer and water service lines when the street is being reconstructed. For questions regarding water and sewer service replacement, contact 612-930-4211 or minnehaha@hennepin.us.
