Construction of the first phase of the Route 150 Widening will happen in coordination with the Route 71/150 interchange improvements. When complete in late 2010, the two projects will significantly improve traffic flow for tens of thousands of motorists in the south Kansas City area. Clarkson Construction Company is the contractor for both projects, which total more than $47 million.

Widening to Four Lanes
Expanding Route 150 from just east of Route 71 in Grandview to just west of Route 291 in Lee's Summit will lower hills, fill valleys and provide two 11-foot-wide lanes in each direction. The contract was awarded for the first phase of construction, from near Route 71 east to approximately Lumpkins Fork Creek. Contracts for segments to the east will be awarded later.

The roadway will include a raised median, curb and gutter, some signalized intersections and reduced speeds along the corridor, reflecting the input from citizens in context of the community's needs, future development, and changing land use.

The Interchange
Reconstruction of the Route 150 interchange at Route 71 includes removal and replacement of the Route 71 bridges over Route 150. The existing diamond interchange will be reconfigured as a single-point, urban interchange, which moves intersecting traffic more quickly by reducing the number of traffic signals. Route 150 will be widened and include separate turn lanes. The ramps will be widened, allowing for multiple turn lanes. Also included will be new bridges carrying the east and west outer roads over Route 150. White Avenue will be extended to the East Outer Road.
