The Alameda-Contra Costa Transit District launched major changes to its bus network over the weekend, affecting nearly 85% of its routes from Richmond to Fremont, officials announced. 

The Realign Service Changes will impact 104 bus lines, with adjustments to frequency, new routes, and the discontinuation of some lines, according to AC Transit officials. 

Some bus lines will run more or less often, others will have new routes to improve connections and reliability, and a few lines will be discontinued in certain areas to make better use of resources, a Saturday press release noted. 

Officials said the redesign was based on two years of rider feedback. 

More than 1,500 bus stops are getting new signs and decals to guide riders, officials said.
