I-44/Range Line Road logo

'Diverging Diamond Interchange'



Project Facts:

Construction: Summer 2012 through end of 2013

Replace I-44 Bridges over Range Line Road

  • New bridge will replace two existing bridges built in 1960.
  • Concrete wall will separate eastbound and westbound I-44 traffic.
  • New bridge will provide 17-foot clearance above Range Line Road.

Build straight, directional ramps in a diamond configuration on I-44

  • Cloverleaf ramps will be taken out, eliminating conflict for traffic speeding up to enter I-44 and slowing down to exit I-44 at same point.
  • Acceleration lanes onto I-44 will be lengthened to allow traffic entering I-44 more time to merge.

Convert Range Line Road to 'Diverging Diamond Interchange'

  • Traffic on Range Line Road will be shifted to left-hand side of the road at new traffic signals on either side of I-44.
  • Range Line Road traffic turning left onto I-44 will have a "free left," without having to turn in front of oncoming traffic
  • Range Line Road traffic traveling straight will return to the right-hand side of the road at traffic signal on the other side of I-44.
  • Signs, pavement markings, concrete islands will guide Range Line Road drivers through Diverging Diamond Interchange.
  • Will build dual right-turn lanes -- Westbound I-44-to-Northbound Range Line Road.
  • Will build dual left-turn lanes -- Eastbound I-44-to-Northbound Range Line Road.
  • Sidewalk built between concrete walls separating northbound and southbound Range Line Road traffic

Traffic Impacts During Construction

  • Lanes on I-44 and Range Line Road closed at various times when traffic volumes are lower.
  • Short-term ramp closings will be needed at times.
  • Range Line Road and ramps may have to be closed for two to three days shortly before the end of the project for final conversion to Diverging Diamond Interchange.

Cost: $9 million (estimate)
