For the past few months, word of the project has spread via news reports, road signs and advertisements.
Anne Staines is with ProProse – the company Caltrans hired to help with outreach.
"Caltrans allotted a very modest amount for the advertising for this, about $200,000. So what we’ve relied on very heavily here is partnering with the local media to increase the visibility. The ultimate evaluation will come on June 2nd when the commuting traffic starts."
The six-week project will cut off one of the main arteries through downtown. More than 200,000 vehicles use that part of the freeway every day.
Local transit agencies are adding extra buses and light rail trains during peak hours. The state has also urged companies to let employees telecommute or work flexible schedules.
Caltrans says the repair is needed to improve a clogged drainage system that is threatening the pavement.
