Section 124 of the California Streets and Highways Code authorizes Caltrans to close or restrict the use of any state highway whenever it considers such actions necessary for these reasons: Closures may also be necessary after major earthquakes or other natural disasters. For example, if the number of lanes is reduced and the direction changed, complete the lane drop before starting the alignment change. If you authorize the devices for use, record the authorization in the daily reports. The cross slope must be no greater than 1:50 (2 percent) and the running slope no greater than 1:20 (5 percent). Verify the contractor protects Type K temporary railing blunt- ends within 15 feet of the edge of the traveled way with temporary crash cushions. Construction signs should be covered or removed whenever they no longer serve a purpose. Anticipated times for sweeping the roadway following grinding or import borrow haul operations to allow public travel with little to no visible dust when the lane is opened to traffic. An inevitable degree of mismatch between the old and new surfaces creates a slight discontinuity that may cause a car to lurch or swerve. 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. Caltrans lane closure charts - btugvo.tamc.info Withhold some payment from progress pay estimates to cover the cost of removing Type K temporary railing. If there are questions as to flagger competency, contact your construction safety coordinator to have them come and observe the flagging operation.

Before ordering the work, and while preparing the task order, check that: CHP support is appropriate for the type of work to be performed. Where possible, compensate for a required reduction of one by an improvement of another. Do not use a reduced regulatory speed limit as a substitute for other means of creating a safe roadway. The cost of covering, uncovering, and removing signs (when they are no longer needed) is included in the contract price for construction area signs. This map shows all of Caltrans current projects (792 ongoing construction contracts).

Process change orders for bid items that require traffic control that are not caused by an ordered change for a contract item or items. They require lane closure charts that specify when and how many lanes may be closed for construction. The California Department of Transportation (Caltrans) and the California Office of Traffic Safety (OTS) today unveiled Safety Sam as their new safety cone mascot. Consider how the shape and the light versus the shadow of falsework openings will appear in daytime and at night. The specifications require temporary traffic screen to have 3-foot-long openings spaced at 200-foot intervals. During routine visits to the project, construction engineers should also review signing, delineation, construction contingency plans, and general traffic handling. Strategies that may result in a net reduction of overall delay for motorists include full facility closures, extended weekend closures, continuous weekday closures, A+B contract specifications, and performance-based, traffic-handling specifications. Significant traffic effectan individual traffic delay of 30 minutes or more above normal travel time during recurring congestion on the existing facility. Confirm the contractor submits a schedule of planned closures in advance as required by Section 12-4.02A(3), Submittals, of the Standard Specifications. Verify the base is shaped to prevent delineators from rolling if stuck by vehicles. When full use is not possible, accommodate traffic by verifying a continuous roadway throughout the length of the project, achieved by using one or a combination of the following: The newly constructed highway or portions of it, A detour where traffic, including pedestrians and bicycles, is diverted over a temporary roadway, Passage of traffic through the work in progress. Caltrans should order early pickup only when traveler and worker safety will not be compromised. When construction activities involve railroad rights-of-way or grade crossings, contact the district railroad liaison agent to confirm that all processes are complete and that the contractor may begin work. Provide the following information to the district railroad liaison agent who will forward it to the Public Utilities Commission: If construction involves structure work, send a copy of the above information to Structure Design. Check the contractors layout work. Do not sever or move a pedestrian route for nonconstruction activities such as parking for vehicles and equipment. When the officer or officers arrive at the project site, the senior CHP uniformed officer will check in with the Caltrans project supervisor who should initiate Form CEM-2101, COZEEP Daily Report. The daily report number will also be the project identifier number.

Verify the contractor offsets the approach end of Type K temporary railing by 15 feet minimum from the edge of an open traffic lane, according to Section 7-1.04 Public Safety, of the Standard Specifications. 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. Samples of activities that may require a contingency plan: A construction contingency plan describes: The contractor verifies or updates the contingency plan at the same time as submitting the written schedule of planned closures. Make every effort to resolve disputes at the lowest level such as between the resident engineer and the CHP coordinator at the local CHP area office.
