Using market-transactions evidence revealed by transportation project contracts, the authors develop forest road and bridge cost equations. The "quality" variable for bridge contracts is bridge size. In the case of roads, the amount of excavation, clearing and grubbing, haul, culverts and surfacing (aggregate) all explain variation in winning contract bids. The resulting equations should be useful in transportation planning as well as in timber-bidding studies. West. J. Appl. For. 1:76-79, July 1986.
