Major Projects in Depth

U.S. 65/Chestnut Exp. (Bus. 65)

Interchange Reconstruction



Project Map

Proposed Project:

  • Convert to "Diverging Diamond Interchange" to improve traffic flow. Opposing lanes on Chestnut Expressway will criss-cross at existing traffic signals. That will enable vehicles on Chestnut Expressway to make a "free left" turn onto the Route 65 on-ramps.

    • New ramp reconfigurations:
    – Northbound Route 65 off-ramp will continue to have dual left-turn lanes onto Chestnut Expressway and will still have a traffic signal.
    – Southbound Route 65 off-ramp will have dual right-turn lanes onto Chestnut Expressway and will still have a traffic signal.
    – Southbound Route 65 on-ramp will have two lanes onto Route 65.

    • Signals will be installed and two right-turn lanes built at Chestnut Expressway/Ingram Mill Road intersection.

    • Under a separate but related project involving the City of Springfield, Greene County and pri- vate developers, the intersection of Chestnut Expressway and Eastgate Avenue will be relo- cated 575 feet east of the existing intersection.

Construction: No timetable is set for construction. However, work could begin as early as Spring 2009. The schedule depends on developers securing their share of the funds needed.

Cost estimate: $5.5 million, shared by MoDOT, the City of Springfield (1/8-cent sales tax) and Greene County and two private developers.

Traffic Impacts During Construction:

  • Expect SLOWDOWNS and DELAYS, especially during busiest travel times
  • Lane closings at night
  • Entrances to businesses, side streets kept open, though narrowed at times
  • Existing Eastgate Avenue access may be limited to right-turns ONLY
