The MTA is expanding its automated camera enforcement of bus stops and double parking to 20 more bus routes across the five boroughs this month.

The rollout is happening in two phases, with 10 routes being added to the program at a time. Starting Monday, vehicles blocking bus stops or illegally double parked on 10 new routes will receive warning notices for a 60-day period. After that, violators will receive summonses starting at $50, with fines increasing to $250 for repeat offenders. Ten more routes will be added two weeks later on Monday, Sept. 30.
