As new RTD rail lines open, Denver’s transit options are expanding. One challenge that comes with the expansion of rail is ensuring that long-time residents can continue to afford their homes and benefit from the improvements. Mile High Connects, an organization that advocates for people who depend on RTD, is calling on decision makers and advocates to come up with housing affordability solutions to accompany the growth of transit. Mile High Connects will launch its call to action on Tuesday.

More on that and other events below.

Tuesday: Mile High Connects hosts Access to Opportunity: A Regional Call to Action to Address Our Gentrification and Displacement Crisis. “We know there is a lot of phenomenal work and deep thinking going on in local communities and neighborhoods around these topics and will be talking about best practice solutions and ways we can work together to comprehensively tackle these critical issues across metro Denver,” says Mile High Connects Executive Director Dace West. 7:30 – 9 a.m. at Cornerstone Baptist Church, 345 South Meade St.

Wednesday: Speaking of transit, the A Line between Union Station and Denver International Airport opens Friday. How will it change the city? An RTD staffer, planners from Community Planning and Development and the Downtown Denver Partnership, and local reporters will discuss the topic on Twitter for this month’s Inside Denver Twitter Chat. This is your chance to ask questions that have been overlooked so far  — like will the stations between the bookends create communities that are truly transit-friendly, walkable, and bikeable? Follow the #InsideDenver hashtag from 12 – 1 p.m.

Thursday: Unite North Metro Denver, the group fighting Governor John Hickenlooper’s I-70 expansion boondoggle, wants you to testify against the project at the State Transportation Commission’s public hearing. The commissioners, appointed by Highway Hick, plan to include the I-70 widening on an official list of projects to be funded by Colorado DOT over the next four years. To tell the powers that be what you think of that, email Jaime.Collins@state.co.us by 5 p.m. today.

Friday: RTD is hosting a grand opening celebration for the University of Colorado A Line between Union Station and DIA, which people can ride free of charge on opening day. Hickenlooper and Mayor Michael Hancock will speak at the ribbon cutting, which will be at 10 a.m. at the DIA station.
