Traffic along I-435 will be shifted to inside lanes to allow the first step of ramp construction, widening outside lanes, begin construction on Holmes and Wornall bridges.
The study limits are from State Line Road to Grandview Road in Jackson County. The study area includes the local service interchanges of State Line Road, Wornall Road, Holmes Road and 104th Street. The study area also includes the arterial roadway network north and south of the I-435 freeway corridor. The study builds on work previously performed by MoDOT and will culminate in a master plan for this section of I-435.
The purpose of this study is to evaluate what types of improvements are needed in this section of the I-435 corridor to provide a safe and efficient transportation corridor for all modes.
This report documents existing bridge plans and inspection reports by MoDOT. The site was visited on May 14, 2014 to develop an initial assessment of the condition of the bridges.
On Dec. 1, 2017, the Missouri Highways & Transportation Commission announced that the Radmacher-Wilson Team -- construction contractor Radmacher Brothers Excavating Inc. and the engineering design firm of Wilson & Company, Inc. -- won the competition for the Design-Build project known as the I-435 South Loop Link. Work is anticipated to begin in spring of 2018 and be fully completed by late spring 2020.
With a budget of $75 million, the department bundled multi-bridge replacements, resurfacing and corridor safety and mobility improvements from the Kansas state line to the Three Trails Crossing interchange into a Design-Build project delivery format. Interested teams competed to provide innovative, goal-driven, results-oriented transportation solutions within a fixed budget.
