Bridge Design

Quincy Engineering, Inc. has a wide range of experience with nearly every type of bridge.  Over the last five years, we have designed or checked over 125 structures in California and Oregon.  These structures have crossed over freeways, highways, and local roads; rivers, creeks, and floodplains; and railroads.  We have designed new bridges, as well as widening, modification, or rehabilitation of existing bridges.  We have certified bridge inspectors to assess the condition of bridges.  Finally, we have completed the load rating of dozens of bridges to determine their load carrying capacity.
Our staff is accustomed to working with state departments of transportation, cities, counties, private developers, utilities, and resource agencies and other key stakeholders whose needs must be met to complete a project successfully.
