Yet another project will be causing delays on Interstate 5 this week, but this one will be quick and it’ll be done at night. Cal-Trans and a contractor will be replacing the huge overhead sign structure on Northbound I-5 at Cypress Avenue. The CHP will run traffic breaks when necessary, but all the work will be done between 9PM and 6AM, with the most disruptive and delay-causing work to be done between 1AM and 4AM. It should be completed on Friday.
