DENVER -- If you're headed out to 6th Avenue near the I-25 interchange at night this week, you will want to allow a little extra time.
Construction crews are demolishing portions of the 6th Avenue bridge that flies over I-25.
The demolition started on Sunday night at 10 p.m. and continued until 5 a.m. Monday. Crews will continue work on the project -- only at night -- until Thursday.
During this time there will be detours for traffic on I-25 going both directions because The demolition will not be safe for drivers to go under.
"Southbound I-25 will be diverted onto 6th Ave and then around onto the Federal ramp down 5th and back onto eastbound 6th where they will renter traffic onto the I-25," said Crystal Morgan, a spokesperson from CDOT.
Northbound traffic will also see a detour but just slightly. Lanes will shift towards the southbound lanes. CDOT says drivers on the 6th Avenue bridge can expect delays in this area for quite awhile because crews are slowly rebuilding the bridge.
It's something Paul Donovan worries about because he's already having to plan in advance to get up and down 6th Avenue.
"It should take me five minutes, it probably takes me 20 minutes. So, four times what it should," said Paul Donovan, who drives on 6th Avenue daily.
But CDOT believes the wait will pay off for drivers because they believe when the 6th Avenue flyover is fixed because traffic will flow much better going into downtown.
The bridge will be complete when the project is done in August 2014.
