Caltrans has expanded its Highway Information Network telephone number, 1-800-427-ROAD, nationwide.

Truckers, tourists and others calling from outside the state can obtain up-to-date information about traffic delays or highway closures.

The new service allows truckers to schedule their own down time until snow-or ice-covered highways reopen.

The toll-free number receives about 4.5 million calls annually.
