Los Angeles Mayor Eric Garcetti joined other L.A. County officials this morning to announce the launch of a new Metro bus line. The NoHo Pasadena Express, which officially begins running on March 1, connects the Red and Orange Metro Rail Lines in North Hollywood to the Gold Line in Pasadena, using the carpool lanes on the California 134 Freeway. The bus will also stop in Burbank and Glendale.

In North Hollywood, the route will meet existing shuttle services to Bob Hope Airport in Burbank. The 501 line has been called the "missing link" in L.A.'s transportation system.

The new 501 line comes at the same time as a number of other Metro expansions. This Saturday, the Metro Gold Line will open six new stations, extending east to Azusa. An extension of the Expo Line is also under construction and will stretch all the way to Santa Monica.

Officials at this morning's press conference encouraged Angelenos to take full advantage of these changes in the public transit system in order to reduce traffic. Metro CEO Phil Washington said he expects at least 1500 rides per week on the new 501 line.
