Existing Conditions – Bridge #12
The existing concrete deck is in poor condition. There have been pop-outs in the past, and future deck pop-outs are possible at any time.
Deck geometry is substandard.
The roadway is not banked sufficiently for the horizontal curve present.
Bridge railing is substandard.

Design Criteria and Considerations
![Page 22: Bristol BF 021-1(33) Regional Concerns Meeting VT Route 116 – Bridge #12 over Baldwin Creek April 27, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062517/56649f355503460f94c52725/html5/thumbnails/22.jpg)
No Action– Additional maintenance required within 10 years
Rehabilitation – Deck Patching– Deck and substructure patching with anodes– Shortest design life– Substandard width and railing
Rehabilitation – Deck Replacement– Longer lifespan compared to patching– Substructure patching with anodes– Width and railing brought up to standard
Full Bridge Replacement– Longest design life– Meets all geometric criteria
Alternatives Considered – Bridge #12
![Page 23: Bristol BF 021-1(33) Regional Concerns Meeting VT Route 116 – Bridge #12 over Baldwin Creek April 27, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062517/56649f355503460f94c52725/html5/thumbnails/23.jpg)
Selected Alternative - Bridge #12
Replace existing deck – Bridge widened by 1 foot on each side to meet
standard– New approach railing and bridge railing– New joints– Meets all geometric criteria– 40 year design life– Utility relocation will be needed– No ROW needed
![Page 24: Bristol BF 021-1(33) Regional Concerns Meeting VT Route 116 – Bridge #12 over Baldwin Creek April 27, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062517/56649f355503460f94c52725/html5/thumbnails/24.jpg)
Proposed Typical Sections Proposed Bridge Rail to Rail = 32’ (Existing is 30’)

Maintenance of Traffic Options Considered
Road Closure with Offsite Detour– Signed by State, regional detour route: 61.3 miles end-to-end
Phased Construction– Minimal impacts to adjacent properties, wetlands, and wooded
areas– Longer construction duration– No ROW needed
Temporary Bridge– One-way with signals, downstream– Biggest impacts to ROW, adjacent properties, and archaeological
resources
![Page 27: Bristol BF 021-1(33) Regional Concerns Meeting VT Route 116 – Bridge #12 over Baldwin Creek April 27, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062517/56649f355503460f94c52725/html5/thumbnails/27.jpg)
Phased Construction One lane, alternating, with a traffic
signal Existing is wide enough to complete
deck replacement with 2 phases No ROW needed
