first double-deck freeway bridge in the state. Part of the design process also utilized computers for various calculations. The Marquam Bridge was built with economy in mind and the public at large reacted unfavorably to the structure's bland aesthetics, which included a formal protest from the Portland Arts Commission. (In particular, it blocked the view of downtown from the Union Avenue Viaduct.) This led to public input in the design of the Fremont Bridge. During Mayor Vera Katz's State of the City address in 2001, she said, "It’s like having the Berlin Wall dividing east and west, with all the subtle charm of the Daytona 500 smack dab in the middle of our city." The bridge crosses over and runs parallel to parts of the now named Vera Katz Eastbank Esplanade. Future Options to replace the bridge historically considered have been to reroute I-5 over the existing I-405 alignment, connecting I-84 to I-5 at the Fremont Bridge interchange, following the US 30 alignment, and removing the Marquam permanently. Another option would build a tunnel under the Willamette River approximately following the existing I-5 alignment, and remove the Marquam Bridge permanently. Proposals have been made to replace the Eastbank Freeway portion of I-5 with a tunnel, connecting with the existing alignment at the Marquam Bridge and the Rose Quarter. This would free up space along the Willamette River for development.
