The Washington Metropolitan Area Transit Authority will change service on many Metrobus routes in Northern Virginia on Jan. 4 in an effect to reduce Metrobus operating costs paid by local governments.

Most of the changes involve service reductions proposed at public hearings last June and September. These changes will save about $1 million in Metrobus operating costs per year.

Decisions are pending on service reductions proposed in public hearings on fares and service held last November. These are not included in the Jan. 4 adjustments.
