The meeting will take place Tuesday, Feb. 12 from 4 p.m. until 6 p.m. at the Mid-America Regional Council offices, located at 600 Broadway Blvd, Suite 200, Kansas City, MO 64105. 


9/25/18: Environmental study begins this month on the Buck O?Neil Bridge

A potential new river crossing to replace the John Jordan “Buck” O’Neil Memorial Bridge has entered the next phase. The Missouri Department of Transportation (MoDOT) and the City of Kansas City, Missouri are working with the Federal Highway Administration (FHWA) to undertake an environmental study, which is required prior to rehabilitating or replacing the existing bridge. The study is being conducted by Burns & McDonnell in accordance with the National Environmental Policy Act (NEPA). Read more here:

Update: 12/4/2019

Crews have performed so far 6 geo-technical borings in the Missouri River. Fifty feet of rock core was obtained below the water surface.  All work is being performed from a barge and is in close coordination with the US Coast Guard, US Army Corps of Engineers and officials with the downtown airport.

The John Jordan “Buck” O’Neil Memorial Bridge (formerly the Broadway Bridge), is a triple arch bridge carrying U.S. 169 over the Missouri River serving as a key regional connection between downtown Kansas City and communities north of the river.

While safe, the bridge is nearing the end of its projected lifespan. Opened in 1956, the bridge recently celebrated its 60th year of operation.  Since that time, the neighborhoods and communities on both sides of the bridge have changed significantly and now nearly 50,000 vehicles use the bridge daily.

The Buck O’Neil Bridge recently underwent a short-term rehabilitation to extend its service life. More significant repairs would need to be made or a new bridge would need to be constructed to provide a crossing that would support continued use well into the future.

To facilitate the evaluation of an improved river crossing, MoDOT is conducting an environmental study. The study is being conducted in accordance with the National Environmental Policy Act (NEPA) and is required before major improvements to the crossing can be made. The environmental study will focus on the U.S. 169 corridor from Missouri Route 9 (MO 9) to I-35, identified as a segment of independent utility in the Planning and Environmental Linkages (PEL) study completed in 2018 by the Mid-America Regional Council, Kansas City, Missouri, and MoDOT. The Buck O’Neil Bridge is part of that corridor

The current environmental study will build on the data collected during the recently completed PEL study to further evaluate options to improve the crossing of U.S. 169 over the Missouri River in Kansas City.

As part of the new study, potential impacts to historic structures, including the existing Buck O’Neil Bridge and other resources in the study area, will be evaluated in compliance with Section 106 of the National Historic Preservation Act, and as applicable Section 4(f) of the DOT Act. The evaluation of impacts to public parks, open spaces, cultural assets, and people and businesses in and around the area will also be conducted.

The study, which is scheduled to conclude in late 2019, will evaluate and document the potential impacts to both the surrounding infrastructure and community and will require significant public input in the coming months. Formal public meetings will begin in early 2019.
