caltrans lane closure charts

Confirm the contractor provides a temporary pedestrian access route (TPAR) nearby, off the traveled way, when the construction activities require the closure of an existing pedestrian route. If a revision is required, the contractor should not close any lanes until the resident engineer has reviewed the contingency plan. The contingency plan identifies alternative or additional equipment, materials, or workers necessary to allow continuing activities and on-time reopening of closures if a problem occurs. Before opening lanes to traffic, remove or obliterate all conflicting traffic stripes and markings. Verify that the contractor schedules and conducts a meeting to discuss the operation of impact attenuator vehicle as required under Section 12-3.23A(4), Quality Assurance, of the Standard Specifications. Confirm the contractor places portable flashing beacons according to the plans and removes them from the traveled way at the end of each nights work. Determine the exact location of the temporary signs and when they are no longer needed for the direction of traffic. Workers may operate vehicles opposite the flow of traffic inside a closed lane only with the prior authorization of the resident engineer. Systems affecting traffic in both directionsInstall the first sign drivers will see traveling in the opposing direction. Create a physical facility that will encourage motorists to appropriately guide their vehicles on the intended path of travel and make it possible for the vehicle to perform as intended. Restore all signs and signals to normal operation. The resident engineer must email service requests, daily reports, cancellation forms, and tracking spreadsheets to the COZEEP coordinator on a monthly basis. For a discussion of final delineation and pavement markings, refer to Section 4-84, Markings, of this manual. LAKESIDE. During these reviews, examine the locations of planned roadside obstacles as well as protective safety devices, signs, striping, detours, falsework, temporary railing, attenuators, and clear recovery zones. Verify that no fixed objects, such as cabinets or poles, will reduce the path width at any point. EL DORADO, Calif. (KTXL) - A rockslide closed off both directions of Highway 50 near Echo Summit for hours Friday. The following COZEEP use criteria do not form an all-inclusive list. Extend entrance ramps through the closed lane by projecting the left shoulder line. The selected speed should be what a driver exercising due care would drive in normal conditions of light and weather. Consult with the transportation management center before temporarily closing a ramp not previously scheduled through the LCS. On every project that requires the contractor to close traffic lanes, the project engineer should assess the need for COZEEP as part of the projects safety review, constructability review, or both. Keep the projects completion dates current in the LCS. They are absolute. 8 CCR 1599, Flaggers, requires illuminating flagger stations during the hours of darkness and lighting should be in compliance with 8 CCR 1523, Illumination, for nighttime highway construction.
