Project Description

Route Y Roadway Improvements

Roadway Design - TWM, Inc. - Roadway Engineering Services for Route Y Improvements
  • LOCATION: Jefferson County, MO

  • CLIENT: MoDOT

  • CONSTRUCTION COST: $3,645,000

  • QUICK FACT: TWM incorporated multiple safety improvements to the design of this project.

Roadway engineering services including pavement management is one of TWM’s specialties. Throughout this corridor in Jefferson County, MO Route Y was an aging roadway and a source of repetitive accidents. TWM’s design provided a uniform lane width for the roadway and a 2’ safety shoulder.  Rumble strips were added along the centerline for the entire 16.3 miles, along with edgeline rumble strips throughout the shoulders and guardrail installation. TWM also completed hydraulic calculations and drainage analysis, replaced all crossroad and two box culverts, provided conceptual cost estimates, and conducted survey/ROW.  Coordination with MoDOT’s local project team was essential to the success of this project.
