The Cape Cod Bridges Project has reached a significant environmental milestone. The Federal Highway Administration has approved the program’s Final Environmental Impact Statement/Record of Decision, advancing the process to replace the Sagamore and Bourne bridges. These vital connections support residents, businesses, freight movement and millions of visitors traveling to and from Cape Cod each year. HNTB's partnership with MassDOT will advance environmental review, preliminary design and stakeholder coordination for this major infrastructure program. The investment will support a more modern transportation system and strengthen access to communities across the region.

HNTB served as the lead design consultant for the South Park Bridge Replacement, delivering final design, for King County, WA Department of Transportation's critical Seattle crossing. The bridge reconnects communities across the Duwamish Waterway while supporting freight, marine, pedestrian and bicycle traffic. To meet resilience goals, HNTB developed innovative solutions including sunken caisson foundations, isolated trunnion frames, and a collapsible center joint, helping create a movable bridge designed to remain functional after lower-level earthquakes and recover quickly following major seismic events. Just as importantly, the project preserved the character of the historic 1931 bridge through salvaged architectural elements and community-focused design, creating a landmark that honors Seattle's past.
