*Caldecott Tunnel Construction September 15-30*

Nighttime Lane Closures Scheduled in Caldecott Tunnel

The following overnight lane closures are scheduled for the remainder of this month in the Caldecott Tunnel on Highway 24:

Bore #1, the tunnel's southern bore:

Bore #2, the tunnel's middle bore:

In addition, crews will be working in Bore #3, the tunnel's northern bore, from Tuesday, September 26 through Thursday, September 28, from 8:30 p.m. each night until 5 a.m. the following morning, and on Friday, September 29 from 9:30 p.m. until 9 a.m. the following morning.

The lane closures in Bore #1 and Bore #2 are scheduled for work on the tunnel's guardrails and other remedial repairs. The lane closures in Bore #3 are for renovations to the tunnel's instrumentation system.

Two bores of the three-bore tunnel will remain open to eastbound and westbound traffic during these lane closures. Some traffic delays are expected and motorists are advised to use alternate routes or public transportation when possible. All scheduled closures will be clearly marked near the tunnel's entrances to advise motorists.

The lane closures are part of a series of closures scheduled to perform urgent repairs in the Caldecott Tunnel. The first phase of these repairs -- which began in January 2000 to replace concrete slabs, improve the tunnel's drainage system, and replace guardrails at the eastern end of the tunnel -- was recently completed. The second phase of the repairs and other improvements planned this year include replacing the original guardrails at the west end of the tunnel and repairing shade screens, as well as improving the tunnel's lighting and instrumentation systems.

Motorists can get the latest information on lane closures and construction activities by calling the Caldecott Tunnel construction hotline at (510) 286-7395.
