Minnehaha Avenue (County Road 48)

Hennepin County, 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

Traffic changes between 31st and Lake streets

Pavement removal is anticipated to bein on the east side of Minnehaha Avenue between 31st and Lake streets approximately mid-to late-week the week of July 18. CenterPoint Energy's crews will then begin working on the gas line north of 31st Street, followed by full street reconstruction by Minnehaha Avenue reconstruction project crews.

In advance of this work, we anticipate switching traffic on Minnehaha Avenue to one lane, southbound only between Lake Street and 27th Avenue starting July 20 (see map). Work in the area and the southbound-only restrictions will continue for several weeks.

Minnehaha Avenue/32nd Street intersection closed

The 32nd Street intersection is closed for the next several weeks. CenterPoint Energy will continue working on their gas main upgrades, and then Minneheha Avenue project crews will fully reconstruct the intersection (including storm sewer work, soil replacement, and curb installation). During the 32nd Street intersection closure, the nearby Minnehaha Avenue intersections at 33rd and 31 streets will remain open. This intersection temporarily operates under an all-way stop until the permanent signal is installed later this year.

Minnehaha Avenue closed between 34th and Lake streets

Minnehaha Avenue is closed to through traffic between 34th and Lake streets and reopened between 38th and 34th streets. Posted detours will direct through traffic around the construction area using Lake Street, Hiawatha Avenue and 42nd Street. Access to local residents and businesses will remain available. The road is anticipated to remain closed to through traffic until approximately November 2016.

2016 closures and detours

Minnehaha Avenue is being closed 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.

Metro Transit

During construction, Metro Transit will detour bus routes around Minnehaha Avenue as needed. Visit Metro Transit's riders alert page to get updated on particular routes in the area.

Construction updates

Crews are working between 34th and Lake streets. Crews continue to remove pavement and will begin replacing soils and structures beneath the road. Traffic on Minnehaha Avenue between Lake Street and 27th Avenue will become southbound only as early as the week of July 18.

The 38th and 35th street intersections will continue operating under 4-way stop conditions until the permanent signal cabinets are installed this fall.

Other projects on Minnehaha Avenue

CenterPoint Energy crews are currently working to replace their gas lines and services on Minnehaha Avenue between 32nd and Lake streets. Parking restrictions are in place. CenterPoint Energy may begin working north of 31st Street as early as the week of July 18.

Please visit CenterPoint Energy's website for project contacts, anticipated schedule, traffic impact information and to sign up for project updates.

The city of Minneapolis has begun construction on 38th Street, west of Minnehaha Avenue. More information can be found on the City of Minneapolis website.

Project background

Design concepts

The county initially studied design concepts for buffered bike lanes, one-way cycle track and two-way cycle tracks on Minnehaha Avenue. County staff recommended 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 will continue improving the gas mains in this corridor in 2016 between 32nd Street and 22nd Avenue. 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.
