The Idaho Transportation Department will close the I-84 westbound on-ramp at Exit 90 in Mountain Home Tuesday morning, Sept. 26. Due to weather conditions, crews were unable to pour concrete last week as planned. This closure will allow paving to continue on the Exit 90 bridge deck over I-84.

Here's what to expect:

• The closure will begin at 3 a.m. and be re-opened by no later than 3 p.m.
• All traffic heading westbound to Boise will be detoured to Exit 95 in Mountain Home.

• The eastbound on-and off-ramps will be open to traffic.
