CHATTANOOGA, TN (WRCB)  --  Crews worked to put up race equipment along Martin Luther King Blvd. Sunday morning.

That is where it will all begin; professional cyclists will take on the Scenic City for this year's U.S.A. Cycling National Championships.

"The road race covers over 19 miles of roads so there's a fair amount of road closures that go along with this," organizer Phillip Grymes says.

Starting at 9 a.m. Monday the women's heat will take off from downtown, complete three shorter laps around UTC, Northshore and the downtown area. That means Market Street Bridge will be completely shut down, a portion of Veterans Bridge will remain open to traffic.

"Yes, its going to be a little bit of an inconvenience, but just plan to take a little more time to move around," Grymes says.  

After the downtown circuit cyclists will head up Lookout Mountain, twice for women, four times for the men.

Broad Street will be closed through 20th Street where traffic will move to the east side of the road from 20th to Lookout Mountain.

For commuters, there's only one way up Lookout on Ochs Highway and one way down via the Scenic Highway.

Organizers say marshals and police officers will line the race route incase anyone gets lost.

"So people that get there and are confused because maybe they're navigating with a GPS or maybe they're not familiar, we'll be able to direct people around," says Grymes.

Cyclists will complete three more downtown laps before ending the race back at the starting line.

The roads will remain closed from 6 a.m. to 5 p.m. Monday, once all the races are completed.

During the race CARTA will provide free shuttle service from the First Tennessee Pavilion to Rock City, Ruby Falls and the upper incline station. It'll leave every 30 minutes.
