Minuteman High School Vehicular & Pedestrian Bridges - Lexington, MA

Project Overview

The timber bridge design for the vehicular and pedestrian bridges at Minuteman High School in Lexington, MA commemorates a local revolutionary war icon, the Old North Bridge. It reflects simplicity of colonial era architecture, clean lines and hearty structural details. It also provided a competitively priced and low-impact alternative to the originally considered culverts. Each of the five bridges are customized to embrace the wetlands’ curves and skews, delivering fluid site circulation and uniting the state-of-the-art vocational high school campus. AASHTO HS-20 load capacity supports traffic from commuters, school buses, and emergency vehicles. The heavy wood grain saturated by the oil coatings pops with a rich tint staying true to the natural warmth of timber and remaining beautiful for future generations at Minuteman High School.
