Before making a decision to approve a change order that would result in a prolonged ramp closure, weigh the results of the study with factors, such as construction costs, travel costs, delay, and safety. Removal of the traffic control systemRemove all workers and equipment from the roadway. Take special care to consider areas in schools or senior citizen center locations. If you cannot contact the local CHP coordinator in advance and the officer reports for duty, the fee will be equal to 4 hours of overtime pay and mileage incurred, if any. For traffic control requirements, refer to Section 12, Temporary Traffic Control, of the Standard Specifications and the California Manual on Uniform Traffic Control Devices (California MUTCD). Verify telescoping flag trees maintain an upright position when being used. Verify temporary or permanent pavement delineation is in place before opening the traveled way to traffic. Caltrans and the CHP have an interagency agreement that is the basis for the Construction Zone Enhanced Enforcement Program (COZEEP). Verify the pavement is clean and dry and the contractor places the channelizers during conditions that meet the required temperatures. For example, anchor guardrail ends and install crash cushions. Verify the planned temporary signal system includes a backup power source and automatic transfer switches. The resident engineer should determine which contractor activities might use COZEEP support. Construction signs should be covered or removed whenever they no longer serve a purpose. Achieving this transition is worthwhile, even though it may extend the traffic control system farther than the minimum necessary to clear the work zone. Try to eliminate surprise elements from temporary roadways. The status in LCS will change to APPROVED. The LCS will notify the contractor by email of the approval or rejection. Obtain the information of trained contractor representatives, including whether they will be requesting or providing a status of closures, or both. Allow only one type of portable delineator on the project. All traffic control devices should conform to Section 12, Temporary Traffic Control, of the Standard Specifications. Results will display in a new window. Before opening a roadway to unrestricted public traffic, the final delineation must be in place on the roadway either by using long-term or short-term temporary delineation or channelizing devices. Review these requirements with the contractors before work starts. Traffic cones are paid for as part of the contract item for the traffic control system. If a system shutdown occurs, planned or unplanned, the contractor should provide flaggers to control traffic until the traffic signals are functioning correctly. Serves as a liaison between Construction, the DTM, and the TMP manager. For example, if the number of lanes is reduced and the direction changed, complete the lane drop before starting the alignment change. Subsequent relocations of each barricade are paid for as extra work using the force account method. LAKESIDE. Work zone activities can disrupt the publics mobility and access.

Materials produced offsite and delivered to a job site, such as asphalt concrete and concrete, can be delayed by events including plant breakdown, loss of trucking, or trucking delayed by traffic congestion because of accidents or by the project itself. Timelines for the contractor and the engineer to meet at the job site, review progress, and forecast when work will be stopped to open the lane, shoulder, ramp, or route to the public. When crossovers require the removal of median barriers or protective devices, review conditions and, where possible, maintain the integrity of the remaining portions of the devices. Refer to Section 7-1.04, Public Safety, of the Standard Specifications, and Topic 902, Sight Distance and Clear Recovery Zone Standards, of the Highway Design Manual. Stationary closures on a traffic lane are 10-97 before placing the first cone on the traffic lane, and 10-98 after removing all the cones from the traffic lane. Establishing continuity is especially necessary if previous traffic shifts have created confusing or conflicting diagonal joints and have eradicated pavement markings. Category 2 devices include barricades and portable sign supports. A desirable standard consists of full width lanes plus an effective width of constructed shoulder. A square joint is even more necessary when asphalt concrete joins concrete, because at night and during rainy weather, the joints often stand out more prominently than traffic lane lines. The following guidelines apply to the color and texture of pavement surfacing materials: The following guidelines apply to speed zones: Frequently, special provisions restrict work on the existing traveled way to a specified period at night. Mobile Verify that all traffic control devices are correctly placed and functioning properly. Do not allow the application of temporary pavement delineation over existing pavement delineation.
