(a) General. Submit a plan to the District Engineer, when indicated or specified, showing or describing the demolition and removal methods to be used for the removal of an existing bridge or culvert, as indicated.

When the structure to be removed is over or under a railroad, also submit the accepted demolition plan to the railroad company's Area Engineer. Do not proceed with the demolition work until written acceptance is received from the railroad company. Provide a copy of this written acceptance to the Department. Notify the railroad company 10 days prior to starting demolition work. Failure to obtain the railroad company's acceptance will require an alternate plan submittal to the Department and the railroad company for review and acceptance.
After removing the existing structure, satisfactorily backfill the area where the existing bridge or culvert was removed. Grade into the existing topography. If directed, place topsoil. Seed and provide soil supplements, as specified in Section 804.3. Use a type and rate of seeding and soil supplements typical for project. Mulch with the type and rate of mulch typical for project, as specified in Section 805.3.
Where the removal area coincides with new construction, backfill voids below the elevation of the bottom of the proposed footings, using acceptable material, then compact, as specified in Section 206.3.
When specified in the proposal or when indicated, leave in place existing substructure portions that do not interfere with new construction, landscaping, or other operations.
Provide documentation (photographs, survey notes) for portions of the structure to remain in place if blasting is used as a method of removal.

(b) Structures Retained by the Department. When indicated or specified in the proposal, remove members or parts of the structure to be retained by the Department. Satisfactorily match-mark the members or parts, and place them within the right of way at an indicated or directed location, within 1,000 feet of the existing structure. When otherwise indicated or when specified in the proposal, load the members or parts, haul them to, and unload them at, a location indicated or specified. Also, if indicated or specified in the proposal, load the members or parts on railroad cars, ready for shipment.

(c) Structures Retained by the Contractor. When not otherwise indicated or specified in the proposal, structures, or parts of structures, will not be retained by the Department.
