BOULDER, Colo. — Work began overnight to remove the controversial bike lanes in Boulder.

The installation in the summer drew thousands of complaints so the city is turning the route back to four lanes for traffic and the expansion of the project has been put on hold.

The move is not sitting well with bikers. They have been fighting to keep the lanes open despite the protests from drivers.

Last week, bicyclists staged a protest with hundreds turning out on two wheels, riding the new lanes to show their support for the experiment. The bikers claim the extra space has made the roads a safer ride.

The smaller bike lanes that used to exist on Folsom Street will remain. The work to bring the road back to its original layout will take about two weeks.
