Council reviews public input on Cascade Bridge project as roundabout emerges as leading — and divisive — option
Summary
City staff presented public‑input findings on the Cascade Bridge/Dankworth intersection, saying the roundabout had the most overall support but also the most opposition; council discussed preservation of bridge elements, NEPA/4(f) implications and safety concerns about proposed tower features.
City staff presented results from a public survey and outreach on the Cascade Bridge and nearby Dankworth intersection at the Burlington City Council work session on April 27.
Mr. Krieger, deputy city manager and public works lead, said the roadway at the intersection has not been resurfaced in 25 years and that design choices affect traffic flow, park property and a National Historic Structure. "The why is one, it's a road that hasn't been touched in 25 years," he said, adding the project triggers 4(f) and NEPA review because park property will be touched.
The staff summary showed the roundabout option had the most support in the public input but also generated the highest level of opposition. "On the intersection, the roundabout was the most supported, but also the most unsupported," Mr. Krieger said. He recommended council give input now so the architect can present refined drawings before the plans-and-specifications stage and before the next public meeting in June.
Councilors and staff also discussed how to preserve elements of the old bridge. Mr. Krieger and others cautioned that any preservation approach should be decided before demolition so city teams can reserve material and budget for display or reuse. The city will need a memorandum of agreement (MOA) with the State Historic Preservation Office (SHPO) tied to the project's federal review. As one councilor noted, "if we want to preserve some of the bridge in some fashion, like what was shown, we better know now before the bridge is demoed."
Safety and maintenance concerns arose around proposed tower or metal‑structure features: councilors worried children might climb tower elements and that ongoing maintenance could replicate past corrosion issues. Staff said those tradeoffs would be part of the design refinement and budgeting discussions.
Mr. Krieger said staff used an online survey and a March public meeting to collect feedback and that consultants (McClure, Klingner) would be asked to provide alternate drawings that move beyond simply reusing a piece of the old bridge. He encouraged council members to consider a preliminary design decision ahead of the June input meeting so feedback can be more targeted.
The city plans another public input meeting in June and will post visual displays and materials as the design process moves toward a plans-and-specifications submission.
