Service on three bus lines impacted by January’s wildfires will return to their pre-fire levels starting Sunday as part of Metro’s twice yearly adjustments, the agency announced Monday.

Metro will also update long-term detours, adjust late-night service to improve bus-to-rail connections, and renumber some routes to improve clarity amid ongoing construction of the Los Angeles Convention Center expansion project and the Wallis Annenberg Wildlife Crossing.

The following routes will be restored:

— Line 602 in Pacific Palisades will reestablish local access and neighborhood connectivity. Route stops and service levels will be unchanged from pre-fire operations;

— Lines 660 and 662 in Altadena will also reestablish local access and neighborhood connectivity;

— Line 30 in downtown Los Angeles will operate via Union Avenue, Olympic Boulevard and Figueroa Street in both directions before returning to Pico Boulevard, as part of the 18-month detour that began Thursday due to the Los Angeles Convention Center expansion project. Some stops will be temporarily discontinued, and riders can use existing Line 28 stops along Olympic Boulevard;

— Line 106 will be renumbered to Line 76 to align with Metro’s standard numbering conventions for downtown routes. There will be no changes to routing, stops or service levels;

— Line 206 in Hollywood will reroute northbound only from the Hollywood Boulevard/Edgemont Street stop to the layover location at Foundation and Vermont avenues. Metro will revise the route via Hollywood Boulevard, Vermont Avenue, Sunset Boulevard, Lyman Place and Fountain Avenue to improve connections to Hollywood destinations. The farside stop at Hollywood Boulevard and Vermont Avenue will be discontinued, with new stops added nearside on Hollywood Boulevard and Vermont Avenue and on Sunset Boulevard at Vermont Avenue;

— Line 60, connecting downtown Los Angeles to Long Beach, will be extended to provide nighttime service to Artesia Station. Three late-night trips will now terminate at Artesia Station instead of continuing to downtown Long Beach with regular owl service to downtown Long Beach beginning at midnight. The adjustment is intended to improve late-night connectivity with the Metro A Line; and

— As Metro replaces its J Line fleet from compressed natural gas to electric-battery powered buses, passenger bays and layover locations will be reassigned to improve operational efficiency at terminals. Lines 70 and 76, which currently uses bays 26 and 27 during owl hours (between 2 a.m. and 4 a.m.) will be relocated.
