The Trump administration could kill state regulations that limit vehicle emissions and promote the sales of electric vehicles. The new EPA rule, expected this summer, could lead to more pollution in Colorado and push the state further out of compliance with federal air quality standards. If that happens, federal officials could cut off funding for highway and public transportation projects in the state.

As Colorado studies rail options along the congested I-25 corridor, experts say few would ride options slower than high-speed rail. But a well-funded anti-rail cabal is likely to defeat any push for bullet trains.

Colorado's economy could support and benefit from a $21 billion high-speed rail system, according to a 2010 report by the Rocky Mountain Rail Authority. The maps presented here come from that report. They offer initial sketches, not detailed plans.

As soon as next year, voters could approve a passenger rail line that would extend along the Front Range from Pueblo and Colorado Springs to Boulder and Fort Collins, with other stops along the way.

When careless drivers severely injure pedestrians, cyclists, police officers and other vulnerable road users, they will no longer drive away from the scene of a crash with nothing more than light penalty. Under Senate Bill 19-175, which Gov. Jared Polis signed into law this morning at the Denver Bicycle Cafe, Colorado became the 10th state to enact legislation that defines vulnerable road users and punishes drivers who hurt them more severely.

Transportation officials launched a statewide listening tour that will give Coloradans the chance to sound off on where limited state transportation dollars should be spent. But even in the heavily car-dependent Centennial State, officials at the state’s highway agency say they want to talk about walking, biking and transit.

Careless drivers who seriously injure people will be taken off the roads under a bill passed Thursday by state lawmakers — the first time Colorado has decided to treat them differently from drivers who only damage property.

Why is Denver still expanding I-70? The move to tear down I-980 in Oakland shows that forward-thinking officials elsewhere get it: The problems associated with mega-motorways in urban neighborhoods outweigh the benefits.

A new report calls for the removal of America's 10 worst urban highways, including Interstate 70 through Denver’s mostly Latino neighborhoods of Elyria, Swansea, and Globeville. Local activists see the report as a chance to renew their calls to stop the project — especially after electing Gov. Polis, who campaigned on cutting vehicle emissions and increasing mass transit.
