The Metro Board of Directors Friday named Jack Requa, its chief operating officer for bus service, to replace Dan Tangherlini as acting Metro general manager.

Tangherlini, whose contract with Metro expires in February, will leave the system Nov. 5 but stay on in an advisory role for another two weeks. Last month, he accepted an offer to join presumptive D.C. Mayor Adrian Fenty’s administration as city administrator. Fenty, the Democratic nominee, is a lock to win the Nov. 7 general election.
