Road Closure/Detour Plans

General
Construction often requires lane closures, detours or road closures. For all projects on the state highway system or impacting the state highway system, detours and closures must be coordinated with the entities responsible for both the road being detoured or closed and the road traffic is expected to use. Policies and procedures for the coordination of road closures and detours are described in the
LGPM Guide
.
Federal Requirements
  1. 23 CFR §630.1006
    – Requires each state to implement a policy for the systematic consideration and management of work zone impacts on all federally funded projects.
  2. 23 CFR §630.1012
    – Requires each project to have a transportation management plan or a traffic control plan. The plan must be consistent with
    Part 6 of the Manual on Uniform Traffic Control Devices
    and with the work zone hardware recommendations in the American Association of State Highway and Transportation Officials (AASHTO)
    Roadway Design Manual
    .
State Requirements
  1. 43 TAC §15.56
    – Requires projects to be designed in accordance with TxDOT procedures, standards and guidelines.
  2. Texas Transportation Code §224.034
    - Requires that before TxDOT enters into any contract for an improvement to the state highway system that will require the closing of the highway, TxDOT must coordinate with public officials from municipalities affected by the closure to avoid adverse economic impacts to the municipality. Any contract for such improvements must include a provision identifying any days the highway may not be closed.
Required Practices
The
LGPM Guide
describes the TxDOT manuals and guidelines that must be used by the LG to coordinate road closures and detours on the state highway system or impacting the state highway system.
