- Little Blue Parkway - 39th to Route 24
Our team provided conceptual planning, preliminary and final design, and construction services for Little Blue Parkway in Independence, Missouri. This 7-mile roadway, which begins at 39th Street near I-70 and extends north to U.S. 24, comprises one portion of the Missouri River Corridor in greater Kansas City. It was designed and constructed in seven phases to help the city manage funds and promote competition for regional construction companies.
The parkway begins as a four-lane urban arterial with interstate access and transitions to a four-lane divided roadway. At the northern terminal of the project, an interim connection to U.S. 24 uses one of the ramps of a future folded diamond interchange to carry northbound and southbound traffic. The ultimate interchange will be completed when the parkway is extended north into an unincorporated portion Jackson County.
The project was completed in accordance with the Missouri Department of Transportation’s Local Public Agency (LPA) policies. Critical issues included coordination with Kansas City Southern Railway for a new grade separation to replace an existing at-grade intersection and design of span and culvert bridges crossing of four FEMA-regulated streams. Environmental impacts of this new arterial roadway through the Little Blue River valley were mitigated by creating new on-site stream and wetland features and by enhancing a local off-site wetland area. Stakeholder communications included open house public meetings and one-on-one meetings to coordinate design with an adjacent property holder who dedicated much of the needed right-of-way.
Multiple intersections were evaluated to develop designs to meet projected travel demand as eastern Independence continues to develop. The team evaluated combinations of signalized intersections and roundabouts to address connectivity with the regional roadway network. All intersections were ultimately designed as signalized intersections. We also designed a new continuous water main ranging in size from 24 inches to 36 inches parallel the parkway’s alignment, as well as 12-inch waterline connections along several intersecting streets.
