Construction to remove vehicle lanes to make way for wider bike lanes is set to begin Monday in Boulder.

The Daily Camera reports that construction is expected to last two weeks as the city moves ahead with the "right-sizing" pilot program for some busy streets.

Crews will remove one vehicle lane in each direction in selected areas and widen the existing bike lanes. Bright green markings will be added to the bike lanes as well as protective bollards, or short, flexible posts.

Transportation planners and cycling advocates say the project will make bike commuting safer and would bring comfort to those who are currently too afraid to ride on streets.

But some residents are skeptical. They worry the plan could increase congestion, possibly leading drivers to use side streets instead.
