Detours and access

Bushaway Road is now open between Minnetonka Boulevard (County Road 5) and McGinty Road/Eastman Lane. This allows for travel among Minnetonka, Woodland and Wayzata. 

Bushaway Road remains closed to through traffic north of McGinty Road/Eastman Lane until the new bridge over the railroad is constructed. The bridge is expected to be complete November 1. 

All truck and through-commuter traffic should use the designated detour following Minnetonka Boulevard (County Road 5), Interstate 494 and Highway 12.

Construction updates

This information was updated September 16, 2016 

Railroad corridor

Now that the concrete pour has had time to cure, crews will be removing the forms (wooden molding) from the bridge deck. Forming and pouring of additional segments of the bridge is also underway. Further along the railroad corridor, workers continue driving sheeting for retaining wall P. The bridge is scheduled to open November 1. 

Minnetonka Boulevard to Eastman Lane/McGinty Road

This roadway is scheduled to open after 7:30 p.m. on September 16. Crews will continue working in the area on the pedestrian and bike trails, sidewalks, ornamental railing and other finishing touches for at least a few more weeks. 

Burial mound restoration

Hennepin County and the Minnesota Indian Affairs Council (MIAC) are working on restoration of Native American burial mounds on the County Road 101 reconstruction project in Minnetonka. 

Currently, the MIAC and a contractor for Hennepin County are doing further investigation of the site as well as restoration activities. Hamline University is recovering artifacts and disturbed remains, which will be restored in burial mounds. 

Breezy Point intersection redesign

The roundabout has been eliminated and a new curve design has been finalized providing greater sight lines and adequate width for the safe passage of all vehicles through the County Road 101/Breezy Point intersection.

Background

A roundabout was planned in the area of County Road 101 and Breezy Point Road in Minnetonka. Hennepin County had commissioned studies conducted by independent parties, to determine if the burial mounds in this area were still intact. Those studies indicated the mounds were no longer intact and the county could proceed with work in the area.

In fall 2014, reconstruction work began and a consultant archaeologist was on site to monitor excavation. On October 11, 2014, bone fragments were discovered during excavation and work was halted. The consultant immediately notified the county, Minnesota Indian Affairs Council (MIAC) and the Minnesota Office of the State Archaeologists about the discovery. On October 13, the state archaeologist and MIAC began investigating the site. 

Throughout the winter, the crews covered the site and installed fencing to secure the area. 

Project background

The following is from a meeting in 2015

The following is historical information compiled prior to construction.

This is a reconstruction project on County Road 101 (Bushaway Road) in Minnetonka, Woodland and Wayzata. The project extends from north of Minnetonka Boulevard (County Road 5) to U.S. Highway 12 (at Wayzata Boulevard). This project is included in the Hennepin County Bicycle Transportation Plan (PDF).

Environmental Assessment Worksheet (EAW)

Proposed changes

  • Anticipate a predominately 3-lane section where the center lane is a shared turn lane from north of Minnetonka Boulevard to Gray's Bay Boulevard and a predominately 2-lane section from Gray's Bay Boulevard to Wayzata Boulevard, except for intersections of Breezy Point, McGinty, and Wayzata Boulevard.
  • Addition of right and left turn lanes.
  • Intersection evaluation at the County Road 101 and McGinty Rd (County Road 16) intersection. Anticipate a standard (signalized) intersection.
  • Intersection evaluation at County Road 101 and Breezy Point Road. Anticipate a roundabout.
  • 2032 Forecasted Design Average Daily Traffic (ADT) counts along the corridor range from 14,000 to 15,600 vehicles per day.
  • Appropriate spacing of access points (as feasible).
  • Replace deteriorating pavement structure.
  • Reconstruct 23-year-old temporary bridge over BNSF Railroad.
  • Lower tracks beneath reconstructed bridge.
  • Structural retaining walls are anticipated for this project. Locations, costs (versus right of way acquisition), and surface treatments to be evaluated.
  • Design using Low Speed Urban Street Design Criteria (Mn/DOT State Aid).
  • Traffic signal upgrades at the existing signal locations identified above (no new signals).
  • 8 foot multi-use trail on east side of the corridor (except in the area of the Grays Bay Bridge where existing 6 foot shoulder and 6 foot sidewalk will be maintained).

Project needs

Safety

The minimal existing right of way, poor geometrics, an aging roadway, increases in traffic, and an aging infrastructure all create safety concerns for the roadway. Some key areas proposed to be improved include:

  • Breezy Point Curve: The existing roadway takes a 90 degree curve at this location and creates unsafe conditions for traffic along CSAH 101, as well as traffic to and from Breezy Point Road. Roadway curve modifications for visibility and safety are proposed at this location.
  • Sight lines over bridge: The existing bridge over Burlington Northern Railroad is considered functionally obsolete as it has a high roadway crown which causes inadequate roadway sight distances. In addition, the structure is in poor condition. A new bridge with improved sightlines is proposed, and will be coordinated with intersection improvements at CSAH 101 and McGinty Road. Hennepin County staff have an unofficial agreement with BNSF to lower the tracks, depth to be determined.
  • Pedestrian and bicycle movement: The existing corridor is unsafe for bicyclists and pedestrians, given the existing narrow roadway and shoulder widths. CSAH 101 is included in the Hennepin County Bicycle Transportation Plan and an 8 foot off-road multi-use trail is proposed for the east side of the corridor.

Traffic

Traffic forecasting studies show that the Annual Average Daily Traffic (AADT) is expected to increase at a rate of 1.0% per year through the year 2032. This puts future traffic levels over 15,000 vehicles per day. The existing roadway serves over 11,000 vehicles per day. Roadway improvements that include left and right turn lanes, and widened shoulders, will greatly improve the safety of the corridor.

Utilities

The County Road 101 corridor is in need of public and private utility improvements that include:

  • Metropolitan Council Sanitary Sewer: The Metropolitan Council proposes to improve the capacity of their forcemain. Their plans for sewer improvements will be coordinated (and constructed) with the County Road 101 roadway reconstruction project.
  • Wayzata Watermain: The City’s watermain is in poor condition and needs to be replaced. The City’s plans for watermain improvements will be coordinated (and constructed) with the CSAH 101 roadway reconstruction project.
  • Other public utilities in the cities of Woodland and Minnetonka will be improved or relocated as necessary.
  • Private utilities: Hennepin County will work closely with all private utility companies to coordinate necessary relocations. The Cities of Wayzata and Minnetonka propose to have existing overhead utilities buried underground.

Pavement

The last major roadway grading for this corridor was completed in the mid-1950’s and early 1960’s.

  • Pavement condition: Over the years, the roadway has had several overlays. But the subgrade consists of poor soils and is impacted by high groundwater levels. In addition, the existing bituminous roadway edge (adjacent gravel shoulders) is in poor condition at many locations. The corridor is in need of reconstruction to improve these conditions.
  • Water quality: The existing roadway corridor has no provisions for treating surface water before it enters the watershed. The proposed project will include provisions to treat roadway surface runoff, and improve water quality.

The project will prepare a discretionary State Environmental Assessment Worksheet.

Timeline

The following is information from prior to construction, including timeline and approval process.

Item Estimated Start Estimated Completion
Preliminary Design 2006 June 2013
Final Design June 2013 Fall 2013
Cooperative Agreement September 2013 March 2014
R/W Process April 2013 April 2014
Estimated construction Mid-September 2014
Fall 2016

  • As of September 2012, the project has started detail design and development of environmental documents.
  • County, city and consultant staff will continue to work with individual property owners to get input on the design relative to their property – in addition to public meetings and focus group meetings as needed.
  • Construction staging/phasing options will be evaluated.
  • Mn/DOT must approve the final construction plans for State Aid and Turnback Fund compliance. Processing through the Mn/DOT Central Office may be necessary.
  • At the time the final plans are submitted to the municipalities for approval, the Construction Cooperative Agreement, which outlines the cost and maintenance responsibilities for each party, will also be submitted for approval.
  • Because of the complexity of the project, construction is anticipated to be staged over 2 to 3 years. Continual evaluation of the construction timeline will be performed as the project develops.

Funding

The project is being designed to meet State Aid Design Requirements. Funding for the project will include State Turnback Funds, County State Aid Highway Funds and local funds.

Municipal contributions will follow the county policy for cost participation and will ultimately be outlined in the Construction Cooperative Agreement. The project has received municipal consent from all cities involved.
