UDS staff participated with the City of Portland team that worked with the bi-state, bi-city and considerable consultant group that was working to develop a replacement crossing of the Interstate 5 Freeway bridges between Portland and Vancouver, Washington. UDS staff worked with the project team and associated committees for over 5 years, helping to explore, develop and collaboratively produce numerous products, including new design guidelines for the project, development scenarios for the EXPO Center site, urban design concepts for Hayden Island, and new bridge design alternatives for the local bridge connection across the North Portland Harbor.
