ST. JOSEPH, Mo. – The intersection improvement project at Route 116 and U.S. Route 69 in Clinton County is moving into Phase 2 of construction soon. Phase 1 of the project, bypass construction, is now complete.
For Phase 2, Amino Brothers Co., Inc. of Kansas City, working with the Missouri Department of Transportation, will shift traffic from Route 116 onto a one-lane bypass constructed on the south side of the intersection beginning Thursday, May 19. Shifting traffic allows the contractor to begin construction of a roundabout at the intersection. Temporary traffic signals will regulate traffic on the single-lane bypass. This traffic pattern is expected to continue through late July. Drivers should expect delays.
U.S. Route 69 south of the intersection will remain closed from just north of 251st Street to Route 116 for the duration of the project, which is scheduled to continue through late August. Access to 251st Street will remain open.
A third phase of the project is currently scheduled to take place from mid-July through late August. During Phase 3 the south leg of the roundabout will be constructed, and the bypass will be removed.

When complete, the roundabout is expected to increase safety and reduce fatal and disabling crashes at the intersection. Roundabouts reduce the number of impact points, eliminate the impact points that result in t-bone crashes, and force traffic to slow down while merging at gentler angles. All these greatly reduce the possibility and severity of crashes.
