The arrival of the USA Pro Challenge bicycle race into the Denver-metro area this weekend means thrills for fans and lots of street closures along with bus and light rail rerouting for residents.

To prepare for the race finale in Denver on Sunday, Denver officials will close some key downtown roads starting at 6 a.m: Broadway from Colfax to 13th Avenue; 14th Avenue from Cherokee to Lincoln and Bannock from Colfax to 13th Avenue.

Regional Transportation District bus route 16 will also experience delays in Golden from Saturday 4 p.m. through Sunday 6 p.m.

On Sunday, starting at 8:30 a.m., Colfax will be closed from Grant to Speer and Cherokee will be closed from Colfax to 13th Avenue.

Lincoln will be closed from 17th Ave. to 13th Ave., starting at 1 p.m.

Riders are expected to enter the Denver city limits at 29th and Sheridan around 2:30 p.m., according to Denver officials. They will then speed through four fast laps around downtown — 17th Avenue and City Park.

Until they enter the Denver circuit at Colfax and Fox downtown, all road closures will be rolling, which should have limited impacts on motorists and residents, says Denver Public Works.

Riders are expected to cross the finish line about 3:45 p.m.

There will be rolling closures at 29th and Speer until about 3 p.m and by 5 p.m. 17th Avenue should reopen.

Colfax from Bannock to Broadway reopens by 6 p.m. as does 17th Avenue.

The RTD bus routes on Sunday that will experience delays and detours in Denver will be: 0, 1, 6,8,9,10, 12, 15, 15L, 16, 20, 24, 48, 52, 83L.

Bus routes in Lakewood that will see some delays and detours on Sunday will be : 28, 31, 32, 51, 76.

As far as light rail in the metro area, D Lines will be temporarily rerouted to Union Station from 1 p.m. to 4 p.m. and H Lines will be temporarily ending at Colfax/Auraria Station from 1 p.m. to 4 p.m. A shuttle train will provide service between the Theatre District/Convention Center Station and 30th and Downing.

On Monday, starting at 5 a.m., Broadway from Colfax to 13th Avenue, Cherokee from Colfax to 13th Avenue, 14th Avenue from Cherokee to Lincoln and Bannock from Colfax to 13th Avenue will reopen.

There will be no interstate closures as a result of the race, say officials. Traffic accessing downtown from northbound I-25 should use the Auraria Parkway exit which will provide access to downtown via Market Street.

Rockies fans heading to Sunday’s game at Coors Field can access I-25 and exit at 20th Street and Park Avenue West.
