DENVER (AP) — A smartphone app that has been helping Colorado travelers track traffic on Interstate 70 has added details for part of I-25 too.

The Colorado Department of Transportation launched the CDOT (c-dot) Mobile app in September with real-time information on highway conditions and traffic on I-70. On Thursday, the department added information on the I-25 corridor between Colorado Springs and E-470 in the northern Denver suburbs.

CDOT operations director Ryan Rice says the app has had about 50,000 users so far.

Future phases of the app will focus on other major highways in the Denver metro area and the rest of the state.
