Districts Impacted
Updated 10/23/2023
Intersection improvements are underway following a study of the crash history from 2015-2019 at the intersections of Grundy County Route 6/Route 146/Route W and Route 6/NW 30th Avenue showed that turn lanes may have prevented more than 50 percent of the crashes at Route 146/W and more than 83 percent of the crashes at NW 30th Avenue.
These geometric changes include widening Route 6 at both intersections and constructing dedicated left and right turn lanes in both directions to improve turning and reduce conflict points for the traveling public.
Project Progress
MoDOT's Planning and Design team, along with a consultant team, are designing a project which will add dedicated right- and left-turn lanes for both directions of traffic on Route 6 at Route 146 and 30th Avenue, just west of Trenton.
MoDOT's Right of Way team has completed all necessary right of way acquisition for the project.
This intersection improvement project went out for contractor bids as part of MoDOT's Oct. 21, 2022 letting. At their November 2022 meeting, the Missouri Highways and Transportation Commission awarded a $4,007,216.56 contract to Phillips Hardy, Inc. to complete the project.
The Notice to Proceed date for the project was Jan. 3, 2023. This is the earliest date the contractor can begin work.
- Phase 1: 30th Avenue intersection – complete.
- Phase 2: Route 146/W intersection – complete.
