Madison Beltline Safety and Operations Study

The purpose of the project was to identify areas along the Madison Beltline for operational and safety improvements. There were 18 existing interchanges along this corridor. Short-term improvements were recommended to address critical safety problems and to maximize the utility and capacity of the existing infrastructure.

DAAR performed data collection for the project, including recreating the alignment for the entire corridor from USH 14 in Middleton to CTH N east of Interstate 39/90/94. Geometric and other deficiencies were identified using as-built plans, pavement inspection reports, bridge information from the Highway Structures Inventory System (HSI), other pertinent documents and field reviews.

Project Deliverables:

  • Complete inventory of existing Madison Beltline roadway, interchanges and bridges
  • Deficiency analysis of Beltline geometry, cross-sectional elements, pavements, bridges and drainage
  • Crash analysis
  • Turning movement counts
  • Identification of short-term improvements to address corridor deficiencies
  • Conceptual plan development for short-term roadway improvements
  • Conceptual plan development for short-term interchange improvements
