Route 45 is a critical east/west route and traffic is expected to increase substantially by the year 2030. These improvements will accommodate development, and most important, improve traffic safety. It will also create a safe, efficient, environmentally sound, and economical transportation facility that meets the needs of the area.

Project Update: 6/2/17: Drainage installation from Brink Myers Rd. to Nevada/Timber Ridge is nearly complete.

The north side of the cross road box culvert has been installed to the west of Nevada and will extend to the east of Timber Ridge Rd. The extension for the box culvert is not expected to happen for several more week and will not occur until traffic is reopened towards Brink-Myers.

Paving has begun on the southeast corner of the new roundabout and will continue towards Brightwell for the next couple of weeks.

Also upcoming, pavement will go from Brink Myers Rd. to Nevad/Timber Ridge Rd. The installation of a roundabout will be built at the intersection of Route 45 and Brink Myers Rd. across from the fire station.

Concrete pavement will be poured from the roundabout to half way between Brink Myers Rd. and Nevada/Timber Ridge. Paving will resume and continue through to Nevada/Timber Ridge.

Project Update: 5/2/17: The installation for the new drainage system from Brink Myers Rd. to Nevada/Timber Ridge is nearly complete. New box culverts are soon to follow. New pavement will go from Brink Myers Rd. to the half-way point between Brightwell Rd. and Nevada/Timber Ridge Rd. The installation of a roundabout will be built at the intersection of Route 45 and Brink Myers Rd.


Project Update: 3/30/17: Crews have been grading and installing drainage structures along Route 45 from Brink Myers Rd. to Nevada/Timber Ridge Rd. This work is expected to be completed in the next 2 to 3 weeks (weather permitting) after which crews will then begin to lay base for paving.

Pavement will go from Brink Myers Rd. to the half-way point between Brightwell Rd. and the Nevada/Timber Ridge Rd. intersection. A roundabout will be built at the intersecton of Route 45 and Brink Myers Rd. across from the Station. Be aware of future traffic shifts at this intersection.

Reminder: Route 45 will be closed between Brightwell Rd. and Timber Ridge Rd. now through June 30, 2017 (weather permitting). Eastbound and westbound traffic should utilize signed detours for this closure.

What is MoDOT doing and how will this benefit me?

MoDOT will continue to widen Route 45 to four lanes from I-435 to Route K. This project will also include retaining walls along the road, adding a roundabout, and building a trail that begins at Route K and ends at Brink Myers Road. The goal is to increase capacity for more vehicles, improve intersection safety and increase driver sight distance by flattening the hills.

Recent Activity:

Phase 2 of the project has begun and Phase 1 will be subsequent to Phase 2 beginning in the spring of 2017. Phase 3 is expected to begin in later summer of 2017.

Back on Monday, Oct. 24, 2016, the final phase of the Route 45 widening project kicked off with a ground breaking ceremony.

Overview of Project Phasing:

  • Phase 1 - Construction of the round-about at Brink Myers Road and removal and replacement of roadway between Brink Myers Road and Brightwell Road. (7 to 9 months)
  • Phase 2 - Removal and replacement of roadway between Brightwell Road and the Nevada-Timber Ridge Intersection (3 to 5 months)
  • Phase 3 - Removal and replacement of roadway between Nevada-Timber Ridge Intersection and Route K. (3 to 5 months)

Maintenance of Traffic:

MO-45 will be closed to through traffic during phases 2 and 3. Motorists will be detoured using I-435, Route 152 and Route K. Local traffic will be allowed to access their property using reduced speed limits and caution. This will allow all residents to enter and exit their properties and not jeopardize worker safety.

Completion Date:

  • October 31, 2017
