Transform 285 @ 400 Preparing for Abernathy Road DDI

The Transform 285/400 project has opened several new movements along SR 400 in the past few months in preparation of the Abernathy Road Diverging Diamond Interchange (DDI).

  • SR 400 northbound mainline lanes have been shifted to collector-distributor (CD) lanes between Hammond Drive and north of Abernathy Road.
  • Opened a new Hammond Drive off-ramp from SR 400 southbound.
  • Shifted the SR 400 southbound mainline lanes and local traffic to Hammond Drive off-ramp and Abernathy Road off-ramp to CD lanes.
