We're starting at the Bay Bridge and will be airing travel advisories on the radio.
There will always be at least two lanes open on Coastal Highway, but we will be completely taking up the old road.
For each day past the May 12 deadline the contractor will be fined $3,000.
At this time of year there are approximately 19,000 cars per day traveling from 589 to Coastal Highway that will need to be diverted.
