FHWA's recently released Manual for Design, Construction, and Maintenance of Orthotropic Steel Deck Bridges
(FHWA-IF-12-027) presents a comprehensive guide to this technology for bridge design.
In situ materials and structural assessment of stress-laminated deck bridge
treated with chromate copper arsenate.
5-m long open deck bridge
located in Western Canada consisted of one 46-m deck truss, and three deck plate girders measuring 21.
It is important that the load distribution factors for FRP deck bridges
must be evaluated in a way that the supporting steel stringers are appropriately designed.
State project manager Michael O'Dowd said he submitted a request to advertise for bids for final design and construction of a five-arch deck bridge
several days ago, while controversy continues among local officials over the design.
Seim agrees: "Designers will create a successful orthotropic deck bridge
if they use these codes," he says.
Tenders are invited for removal of the existing bridge and the construction of a new 76~-0" single span, 10 degree skew, type vi concrete i-girder and concrete deck bridge
with steel h-pile foundation, concrete abutments, sl-1 guardrail and all appurtenances.
Murray said yesterday that there are pros and cons to both designs and the more costly bridge will require four years to construct compared to two years for the five-span deck bridge

The current timber deck bridge
across Mt Emu Creek is single-lane, suffers substandard curved approaches, cannot carry heavy loads and is becoming increasingly expensive to maintain.
I think they overestimated the cost of the through arch and underestimated the cost of the flat deck bridge
The project will also reduce the number of spans from three to one resulting in a new single-span ballasted deck bridge
which will reduce overall maintenance cost.
