Transit authority General Manager Richard Sarles plans to commemorate the official opening of seven escalators that have been rehabilitated at Union Station.

The escalators are at the First Street entrance, near the MARC corridor. Rehabbing them cost $2.2 million and has been underway for more than a year and a half.

Sarles will also mark official opening of the third new escalator at Foggy Bottom station. In July, Metro opened the first new escalator at the station. It was the first time in more than a decade that Metro had installed a new escalator in an existing station.

The canopy on the escalators will be installed in the first few months of next year, according to Metro’s chief spokesman Dan Stessel. Work is also underway to build a staircase at Foggy Bottom.

The escalator work is part of Metro’s $150 million effort to try to make its more than 500 escalators more reliable.

The authority also plans to shut down the south entrance at Dupont Circle to replace all three escalators there, starting in February 2012. That work is expected to take 10 months.
