Metro to Enhance Bus Service on Selected Lines Effective Sunday, Dec. 16
Effective Sunday, December 16, Metro will enhance service on selected Metro Bus lines by making some minor changes in an effort to improve the efficiency and effectiveness of Metro bus service.
Additional midday and weekend bus service will be added to Line 40 (Downtown LA-South Bay Galleria via MLK Blvd.) along Crenshaw Blvd. and La Brea Avenue serving the Hawthorne/Lennon Metro Green Line Station.
Metro will add service to improve the frequency of bus service on the Metro Silver Line operating along the Harbor Freeway Transitway between the Artesia Transit Center and downtown Los Angeles during weekday morning peak periods. Silver Line service improvements during the morning peak period will operate from every 10 minutes to every 8 minutes. In addition, late night service along the Silver Line will improve from every 60 minutes to every 40 minutes.
