Caltrans officials plan to repave Sepulveda Boulevard south of Los Angeles International Airport at night in the next few days.
At least one lane will remain open for vehicles heading in either direction on state Route 1 while the work is underway on certain nights through the end of June.
The project will repair pavement on Sepulveda Boulevard from Rosecrans Avenue to Imperial Highway, a distance of more than two miles, said Caltrans spokesman Michael Comeaux.
Starting 11 p.m. Monday night, northbound lanes of Sepulveda Boulevard will be repaved, lasting until 6 a.m. Tuesday.
Similar lane closures, either northbound or southbound, are expected on most nights through the end of June, although rain could cause postponements.
American Asphalt of Corona has the $1.5 million contract to apply slurry seal.
Late night or early morning drivers hoping to avoid the expected north-south congestion can use Aviation Highway or the San Diego (405) Freeway to the east.
Caltrans officials have been anxious to lay pavement, to show voters that the new state gas tax and vehicle registration fees imposed by the legislature are underway.
Some Republican politicians are using a initiative to overturn the tax, and in the process attract political support. Others, aligned with business interests, support the tax as investment in the future.
