Napa's roundabout construction: Threading the needle


Since the start of construction in early June of the three roundabouts at Highway 29 and First Street, thousands of Napa motorists have had to weave their way each day between concrete safety barriers, roaring heavy equipment and mountains of dirt.

There are slowdowns and backups at various times of the day, but traffic continues to flow safely, said Eric Whan, deputy city public works director.

While negotiating sharp turns, motorists get to glimpse the reworking of the junctures of First and Second streets with California Boulevard and First with the freeway on- and off-ramps to accommodate the three roundabouts.

The $11 million project, which is intended to improve traffic flows and reduce delays, is set for completion in 2020. Because the project is being accelerated, the finish may be in the first half of the year rather than the end, Whan said.

The two roundabouts serving First and Second streets may go into operation before the end of this year, which is when the one-way directions of these streets will flip, Whan said.

These two roundabouts would be functional, with some work remaining, he said.

Between now and then, travel routes through the construction zone will be modified more times as construction enters new phases, Whan said..
