Sens. Chris Romer of Denver and Dan Gibbs of Silverthorne, both Democrats, want to use moveable barriers to temporarily add an eastbound lane on weekend afternoons when the highway is jammed with people returning to the Front Range from the mountains.
They plan to introduce the bill Monday.
The Colorado Department of Transportation Department says it’s been considering the idea for a year and is currently studying whether it’s safe. Department spokeswoman Stacy Stegman says the legislation isn’t necessary.
The department is looking at buying the barriers. The proposed legislation would allow the state to lease them from a private company.
