Here is the news release from Metro:
Effective Sunday, June 23, Metro will make a series of minor changes to improve the efficiency and effectiveness of bus service including more midday service on the popular Metro Orange Line and better connectivity to Olive View Medical Center in the San Fernando Valley.
Metro will provide additional midday service on the Metro Orange Line improving the frequency of buses from every 10 minutes to every 8 minutes on weekdays. Additional service also will be added to improve late night service.
Olive View Medical Center in the San Fernando Valley will get better connectivity by renumbering existing Line 290 to Line 90 so passengers will now be able to board Line 90 buses with continuous service to and from the medical facility.
The City of Los Angeles is launching the Bringing Back Broadway project which will reduce traffic by one lane in the southbound direction on Broadway in Downtown LA for sidewalk improvements between 1st and 11th streets. To reduce bus congestion and ensure bus schedules are maintained, Metro will move the southbound buses on Lines 30/330 and 40 from Broadway to Spring St. Lines 45 and 745 will remain on Broadway in both directions. Once the streetscape plan is complete on Broadway, all northbound lines will have major stop changes.
Below is a list of planned service changes and route modifications to start on June 23, 2013. For complete details, look for revised timetables on metro.net or on buses during June.
