County Road 101 (Bushaway Road)

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).

Proposed changes

  • Anticipate a predominately 3-lane section where the center lane is a shared turn lane from north of Minnetonka Blvd 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 Blvd.
  • 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 CSAH 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 CSAH 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

Estimated timeline for project design schedule

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
Construction April 2014 November 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.
  • Estimated construction start is spring 2014.
  • 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.
