I-84 Bridge Work – Centennial Way

I-84 Bridge Work - Centennial Way

ITD is resurfacing a bridge and two ramps on I-84 that run over the Boise River near Centennial Way in Caldwell. The project will extend the lifespan of the bridges and surface.

Project overview

The Idaho Transportation Department is starting bridge and ramp work on I-84 near Centennial Way on March 18. The work will take place on an I-84 bridge and two adjacent ramps off Centennial Way that run over the Boise River in Caldwell. The project will extend the lifespan of the bridges and surface.

(Please note, this bridge work is not part of the improvement project happening from Centennial Way to Franklin Road later this summer. For more information about that project, please visit: Centennial Way to Franklin Road.)

What to expect during construction

  • The bridge on I-84 will be worked on first
  • The I-84 westbound-on ramp and eastbound-off ramp at Centennial Way will be worked on second
  • Crews will work behind safety rails during the day
  • Nightly I-84 lane restrictions are expected:
    • Mon. – Fri.: 9 p.m. – 6 a.m.
    • Sat. – Sun.: 9 p.m. – 9 a.m.
  • Drivers will be detoured to Exit 28 during closures
  • An advisory speed limit will be in place
  • Work zone will be tight

Resurfacing the bridges

The bridges will be resurfaced to extend their lifespan. The ramps will be redone using an epoxy overlay while the I-84 bridge will be resurfaced with silica fume concrete. To learn more about how crews will prepare the bridges using hydro demolition, check out the video.
