Sometimes through traffic tends to follow an exiting vehicle. Where the prevailing speed of the approach is limited by alignment, the design speed should be equal to the prevailing speed of the approach roadway. When the work has safely progressed beyond the supplemental taper, remove the upstream taper and tangent. The CHP has 5 working days to notify Caltrans if the actual travel time, mileage, or both, are greater than the allowances estimated on the daily report.
