Inquiry #9: The staging at Tennyson (stages 1 and 4) needs serious reconsideration by CalTrans. The idea of attempting to laydown 700+lf of k-rail each night, then demoing' the road and attempting to either put back temp AC pavement (12"+) or quickly install a median double curb (all in the course of one night shift), and then pick up the 700+lf of k-rail and fully restore the road is unattainable ... especially in the course of 6 nights. By my measurements there is enough room to laydown permanent k-rail and still maintain 4 lanes of traffic during the day .... we would then take one lane at night. Please provide new staging.
