Castle Rock to launch free on-demand transit service July 31

Castle Rock will add free on-demand transit on July 31, giving residents another way to get across town without driving or paying for a rideshare. Douglas County commissioners approved $1,991,720 to expand Link On Demand into Castle Rock as a pilot program, and the Town Council approved the intergovernmental agreement on April 21.

Link On Demand works as an app-based microtransit service that lets riders request shared trips within designated service zones. The county already says the service runs in Lone Tree, Highlands Ranch, Stonegate and parts of Parker, making Castle Rock the newest town in the network of free rides that has spread through south Denver’s suburban edge.

The expansion is aimed at riders who have the fewest transportation options now: people heading to work, doctor’s appointments, the grocery store or dinner with friends. That is a narrower and more practical promise than a commuter rail line or full bus grid, and it is meant to fill the gap between the town’s existing limited transit options and the daily trips many residents still have to make.

Castle Rock’s transit information already says the town supports rides for seniors through the Castle Rock Senior Center and offers medical rides up to Lincoln Avenue in Lone Tree and to RidgeGate Station. The new service should matter most to older adults, people with disabilities, households without a second car and anyone who cannot justify a long car trip for a short errand but still needs to move around Douglas County.

The county has framed the program as a free, app-based alternative that functions like a rideshare service, but without the fare. That makes the July 31 launch less like a convenience perk than a public mobility investment, though the county is still treating it as a pilot rather than a permanent buildout. The key questions now are whether Castle Rock residents use it enough to justify the spending and whether the service reaches the destinations that matter most inside town, from neighborhood job sites to the grocery store to medical stops in Lone Tree and south Denver.
