Due to the construction of the I-25 North Express Lanes Project, both north and southbound lanes will be closed.

According to the Town of Johnstown, between 9 p.m. on Wednesday, August 21 and 5 a.m. Thursday, August 22, I-25 will be completely closed in both directions so construction crews can work on the 402 bridge.

Detour for northbound lanes will be brief, however the southbound detour is more extensive.

'Northbound traffic will detour onto the CO 402 off-ramp Exit 255, continue through the roundabout on the SE Frontage Rd and proceed onto the current northbound I-25 on-ramp at River Ranch Parkway,' the Town of Johnstown posted on Facebook.

'Southbound I-25 traffic will detour onto the CO 402 off-ramp Exit 255 and turn south on Co Rd 7 to east on E Co Rd 48 to the southbound I-25 on-ramp.'


I-25 is scheduled to only be closed on Wednesday night, however that is weather permitting.
