Maryor Antonio Villaraigosa reiterated that the construction on the 405 is on schedule, when he addressed the media almost 16 hours into closure.
"So far, and I do say 'so far'," the Mayor warned of the tenuous nature of the construction.
Mike Barber, a Metro project manager who is helping head the project, reiterated the Mayor's words on the construction's delicate state.
Barber said that the reports that the construction is currently ahead of schedule are true, but that is because they "haven't had problems," and said they may lose time if they come upon any stumbling blocks during the process.

Deputy Chief Kirk J. Albanese said that they have had several instances of people, either on vehicles or foot, entering the freeway, which he said would result in arrests.
"If anyone comes onto the freeway, they will be arrested," said Albanese.
Villaraigosa said that while the first day of the closure has gone smoothly, tonight could present a different story with a home Dodger game and other events around the city.
"Don't get in your car unless you absolutely have to," said Villaraigosa. "But if you absolutely have to, car pool."
Sheriff's Lt. David Thompson of the Malibu Station said Saturday afternoon that the traffic is moving on Pacific Coast Highway and "pretty ligh" for a weekend.
