As MTC continues toll system testing on the future I-680 Contra Costa Express Lane, drivers will see test messages on the Variable Toll Message Signs starting Monday, March 27, 2017 northbound from Alcosta Blvd. to Crow Canyon Road. After successful testing in this area, the test messages will move to other areas of the corridor through April 2017.
Drivers can expect to see dots, test toll amounts (e.g. $1.00), and test notifications such as “TEST 1 – NO TOLLS” or “TEST MESSAGE 2”. All toll system signs are affixed with static “Under Construction” stickers. While motorists will see prices on the signs, cars will not be tolled during the tests.
