Stringers: N Girders: 3 See field notes sheets 5 & 6. The rating is due to extensive section loss with perforations in the webs and flanges of girder ends and end diaphragms at the pier. The rolled steel girders exhibit areas of peeling paint with moderate to heavy rust throughout. The webs for interior girders (G2-G5) over the pier in both spans exhibit severe to laminated rust with section loss up to 4' long x full height x 11/16" deep (Original thickness: 0.775"; 88.5% web loss; girder G5 at pier, span 2).

There is active leakage noted on the pier. See field notes sheets 29 & 30 and photo 39. Not visible. Erosion - Rated 8 Scour - Rated 6: There is an isolated 4' diameter x 2' deep scour area beneath the outfall pipe at the west abutment stem. See photo 40. Per Underwater Inspection Report, dated 07/17/2014: "As compared to the 2010 and 2012 inspections, the channel bottom elevations have remained relatively unchanged (less than 1.0' variations) along the abutments and pier. There is evidence of scour up to 2' deep at the upstream (north) nose of the pier and along the east face of the pier". Concrete Crack - Spall: 6 Steel Corrosion: N Paint: N Timber Decay: N Collision Damage: 8 Debris: 6 See field notes sheet 27. See above items.

Rating Channel - Scour: 6 Per Underwater Inspection Report, dated 07/17/2014: "As compared to the 2010 and 2012 inspections, the channel bottom elevations have remained relatively unchanged (less than 1.0' variations) along the abutments, pier and throughout the channel. Near the downstream (south) end of the west abutment, there is a 6' wide x 1.3' deep area of erosion beneath the outfall pipe in the stem. There is evidence of scour up to 2' deep at the upstream (north) nose of the pier and along the east face of the pier. There is no exposure of the abutment or pier footings." See photos 41 &

There are dead trees lying in the channel along the southwest embankment. Per Underwater Inspection Report, dated 07/17/2014: "The channel embankments are well vegetated with a few trees leaning towards the channel". Per Underwater Inspection Report, dated 07/17/2014: "There is no apparent change to the channel orientation. There is increased water velocities beneath the bridge due to a constriction in the upstream (north) channel and a man-made island in the center of the downstream (south) channel. There are abandoned stone piers near the center of the channel in spans 1 and 2 beneath the bridge". The southeast retaining wall exhibits an isolated 4.5 long x 3.5 high x 43 deep void in the stones.

16 Form: BRI-18, Rev. 1/14 Visibility: NOTES / COMMENTS: Character of Traffic: Light to moderate volume with mixed weights. Additional Notes: 1. The bridge identification number is clear and legible. See photo The bridge is logged from west to east with girder G1 at north fascia and the Pawcatuck river flows from north to south, which is consistent with the previous inspection report and bridge plans. 3. The bridge is inspected using a 62' snooper. However, it is recommended to use a smaller snooper due to low clearance between the water and the girders. 4. Local police from the towns of Stonington and Westerly, RI as the bridge is connecting the states of CT and RI. See report table of contents. Additional Comments: Town Letter Submitted No Pending Project Due to the poor and declining condition a new load rating has been requested. 14
