About this file
This document appears to be a set of technical plans for the Bog Dam 4 Bridge replacement project. The plans include an index of 16 sheets covering the project location, design data, quantities, traffic control, typical sections, site plan and profile, structure details, soil borings, cross-sections, and guardrail details. The proposed structure is a 40.58-foot single span steel girder bridge with a timber nail-lam deck, designed for a 15 mph speed limit. The project is located in the White Mountain National Forest in Coos County, New Hampshire. The related federal contract opportunity has a solicitation number of 12445524R0008 and a description of the contractor furnishing all labor, materials, and other incidentals to demolish the existing bridge superstructure and construct a new one using the existing abutments. The contracting agency is the Department of Agriculture Forest Service.

GENERAL NOTES:
1. INSTALL THE SPECIFIED QUANTITY OF ROLLED EROSION CONTROL PRODUCT (EMAT) AND THEN ANY
ADDITIONAL AREAS THAT ARE DISTURBED BY THE CONTRACTOR SHALL BE SEEDED AND MULCHED UNDER THE
LUMP SUM PAY ITEMS.
2. COORDINATE SYSTEM REFERS TO NAD83 NEW HAMPSHIRE STATE PLANES, US FOOT (ASSUMED COORDINATE).
DATUM REFERS TO NAVD88.
3. REFERENCE POINTS "A" AND "B" REFER TO FINISH GRADE AT CENTERLINE AT THE BACK FACE OF THE
ABUTMENTS.
4. PROVIDE SMOOTH TRANSITION FROM EXISTING TO PROPOSED ROADWAY AT REFERENCE POINTS "C" AND "D".
FADE OR EXTEND PROFILE SLIGHTLY AS REQUIRED.
5. SURVEY WAS COMPLETED BY HORIZON ENGINEERING FOR THIS PROJECT ON 11-28-2022.
