Project Alternatives

Corridor Alternatives

Three corridor level alternatives were developed to support the Veterans Boulevard Extension. Each alternative involves a slightly modified roadway section and intersection control features. Development of each alternative is supported through both public input gathered earlier in the planning process and through transportation planning projections for the study area.

Alternative 1 - Standard Intersection

This alternative involves the following elements:

  • Three lane roadway (I.e. one lane in each direction with a center two way left turn lane) with two 10’ foot shared use paths on each side of the corridor.
  • Standard signal-controlled intersections are planned for 64th, 76th and 88th Avenue.
  • Corridor follows the section line from 52nd Avenue to 100th Avenue with an assumed right-of-way of between 150 to 200 feet.

Alternative 2 - Roundabout Intersection Alternative

This alternative involves the following key elements:

  • Two lane divided roadway with 10-foot shared use path on each side of the roadway.
  • Roundabout intersections are planned for 64th, 76th and 88th Avenue.
  • Corridor follows the section line from 52nd Avenue to 100th Avenue with an assumed right- of-way of between 150 to 200 feet.

Alternative 3 - Modified/Variable Alternative

This alternative introduces two new roadway section concepts to provide a variation of the earlier alternatives:

  • 52nd Avenue to 64th Avenue & 88th Avenue to 100th Avenue
    • Three lane roadway (I.e. one lane in each direction with a center two way left turn lane) with two 10’ foot shared use paths on each side of the corridor.
    • Corridor follows section line with an assumed right of way of 150 to 200 feet of right of way.
  • 64th Avenue to 76th Avenue
    • Three lane roadway (I.e. one lane in each direction with a center two way left turn lane), 8 foot parking lane and two 10’ foot shared use paths on each side of the corridor.
    • Roadway alignment is shifted east of the section line to allow for a larger green space on the western edge of the corridor adjacent to Drain 27.
    • 175 feet of right-of-way is assumed.
  • 76th Avenue to 88th Avenue
    • Three lane roadway (I.e. one lane in each direction with a center two way left turn lane).
    • 20 feet of pedestrian, bicycle, and amenity areas on each side of the corridor
    • Frontage roads with parking lanes on each side of the corridor.
    • 175 feet of right-of-way is assumed.

 

All options developed for this alternative assume roundabout intersections for 64th, 76th and 88th Avenue.

Roundabouts North of 52nd Avenue

The current roundabouts located on 44th, 48th and 51st Avenues were evaluated based on both existing and projected travel conditions. Concerns were identified with the current design of those intersections. 

The project team developed two options to revise the current roundabouts to improve traffic flow through those intersections. Drivers would see little change to the intersections, however subtle changes would improve both traffic flow and seasonal maintenance of those intersections. One option would reconstruct the approach of each leg to each intersection to improve traffic flow through the intersection. This option would keep the existing 150-foot diameter circulatory roadway. The 2nd option would reconstruct the entire intersection. This option would increase the circulatory roadway diameter to 180-feet and reconstruct all approach legs.  The project team feels the first option will address both existing and projected conditions in the study area with the least amount of neighborhood disturbance and lowest cost.

Deer Creek Connection

Two potential new connections serving the Deer Creek neighborhood were developed as part of the Veterans Boulevard Corridor Extension Study. The first option involves extension of 59th Avenue across Drain 27 connecting to Veterans Boulevard. The second option involves construction of 62nd Street to connect 63rd Avenue to 64th Avenue. (62nd Street is currently platted road right-of-way.) These connections were mentioned through previous public input and support improved emergency response to the neighborhood. These connections reflect continued demand for travel to areas south and west of Deer Creek, including a new middle and high school in Horace.
