Woods Chapel and the Diverging Diamond

What is the problem?

Woods Chapel Road south of I-70 currently experiences long delays and congestion because of:

  • closely spaced signals are 350 feet apart where desirable spacing is greater than 800 feet,
  • weaving traffic patterns with right turns immediately followed by left turns, and
  • a lack of capacity as northbound traffic predominantly turns left to I-70 westbound

What is the solution?

Two alternatives were evaluated:

  • Modifications to the existing interchange including additional lanes on the bridge over I-70 to accommodate traffic demand and queue storage, and
  • A “Diverging Diamond Interchange” (DDI) that utilizes the existing bridge width.

Both scenarios include widening Woods Chapel Road, widening the I-70 ramps and relocating the South Outer Road.
