New digital speed-limit signs will aid safety, traffic flow in I-84 work zone 
Beginning this week, ITD will deploy variable speed limits within the Interstate 84 construction zone in Canyon County.

ITD has committed to keeping delay impacts to the traveling public on this corridor to a minimum. This has included restricting major work to evening hours and keeping the existing number of lanes as two in each direction open during peak times whenever possible. The department believes implementing variable speed limits will further enhance safety and mobility of the corridor while completing this critically-needed congestion relief project.
What are variable speed limit signs?
New digital signs will allow ITD to adjust the speed limit as needed, based on the level of activity in the work zone. Learn more.
What to expect:
  • ITD will place signs between Karcher Road (exit 33) and Franklin Road (exit 29) interchanges on:
  • Eastbound and westbound lanes of I-84
  • The on-ramps at Karcher and Franklin roads
  • Crews can quickly change the speed limit on these digital signs to actively manage conditions in the work zone.
  • A flashing beacon will notify drivers in advance when speed limits are reduced from 65 mph.
The signs will be removed when construction is complete in summer 2023.
