Seven Bridges, One Corridor Package
As lead structural subconsultant to DAAR, Lynch delivered rehabilitation design for seven bridges along USH 12 between STH 67 and STH 50 - a coordinated WisDOT corridor package covering structure survey reports, load ratings, final plans, specifications, estimates, and calculations.
Detailed design ran the full depth of each structure: abutments, piers, girders, bearings, and superstructures, with construction staging plans that kept traffic moving through the corridor throughout the work.
When a semi-truck impact damaged a girder after letting, the team prepared an emergency addendum and special provision on a fast turnaround - field-responsive structural engineering that kept the corridor package on schedule.
