The Caltrans and SANDAG Build NCC project piloted the use of orange contrasted temporary pavement delineation in California after Caltrans received approval from the Federal Highway Administration (FHWA) to be the third state to experiment with orange lane striping in construction zones.

Temporary orange lane striping is used in construction zones, increasing the contrast with the traditional white lane striping that is removed during construction when lanes are realigned, to help capture the awareness of drivers in construction areas. Orange lane striping has been successfully used previously by three other states: Wisconsin; Texas and Kentucky; and in countries including New Zealand and Canada.
