Flagstaff-area drivers should plan for closures while deck work continues on four I- 40 bridges that carry traffic over I-17 and Beulah Boulevard. The southbound I-17 to eastbound I-40 ramp will remain closed around the clock through Wednesday. Northbound Beulah Boulevard will be closed overnights from Sunday, Oct. 21st to Tuesday, Oct. 23rd. Southbound Beulah Boulevard will be closed overnights from Tuesday Oct. 23rd until Thursday, Oct. 25th. Detours will be in place. Work to repair and replace the decks on the four bridges began eight months ago and is scheduled for completion later this year.
