"Carmageddon" has hit the halfway point in Los Angeles - and so far so good.
There have been no major problems since a 10-mile section of Interstate 405 was shutdown at midnight Friday for construction.
But there have been a few trespassers.
Officials report a bicyclist made it onto the road before getting escorted off by police, a man was cited for driving on the roadway, several people were found putting up a large sign, and a man was caught scaling a perimeter fence.
But the traffic many thought would set off a "Carmageddon" has instead been lighter than normal as crews work feverishly to demolish part of a bridge over 405.
Some officials including Mayor Antonio Villaraigosa are worried that drivers would get complacent and return to the roads on Sunday.
So the warnings continue as the shutdown reached the halfway point as of 2:30 a.m. Sunday. The roadway, one of the nation's busiest, reopens at 5 a.m. Monday.
