After just a little more than a week back in service, one of the elevators at the Bethesda Metro station is not working.

The out-of-service elevator is between the street and mezzanine level of the station at the corner of Wisconsin Avenue and Montgomery Lane.

WMATA officials did not immediately return calls this morning inquiring about the cause of the outage, but the transit authority’s website said the elevator was expected to be back in service tomorrow.

The elevators at the Bethesda Metro station were taken out of service last May for a rehabilitation project and were out of service until Jan. 2, The Gazette reported last week.

Officials initially expected the project to take four months, but the availability of parts and a change in state elevator codes delayed its completion, a WMATA spokesman previously said. Upgrades included a back-up system for the elevators’ emergency call button.

Designers are currently planning an escalator replacement project for the station. Construction is scheduled to start in early 2014.
