Sand-filled barrels to block off Cascade Bridge

Looking to shore up the barricades on either end of the closed Cascade Bridge, the Burlington City Council voted 4-1 Monday night (March 7) to add 40 barrels full of sand to ensure the bridge’s protection.

City council member Matt Rinker was the only “no” vote, as he deemed the barrels too expensive and ineffective. He also thought they would be an attractive nuisance for kids who want to take the lids of the barrels and use them as sandboxes. 

The barrels will cost the city roughly $12,000, breaking down to about $300 per barrel – 20 on each end of the bridge. That includes the price of staff, which is nominal, and the price of sand, which is a bit more expensive.

Mayor Jon Billups said during the council work session the previous Monday (Feb. 28) that the barriers could save someone’s life. Cascade Bridge was closed to vehicle traffic in 2008 and pedestrian traffic in 2019 due to safety concerns, but two vehicles have crossed the bridge since the closure.

The first incident occurred in February of 2020 when a motorist lost control of their vehicle after their brakes failed. The second incident occurred in December of last year when a high-speed chase crossed the bridge. The vehicle was able to scrape through the barriers and cross to the other side, and police did not follow it across the bridge. They were able to apprehend the suspect later.

Assistant city manager for public works, Nick MacGregor, said the proper signage indicating that the bridge is closed is up. After Billups asked him to look at ways to enhance the barricades, he suggested the barrels – the same kind found on highways to reduce the impact of traffic accidents. MacGregor said he and Billups initially discussed installing Jersey barriers (concrete slabs that measure 32 inches high with slanted sides), but that proved to be a problem with liability for the city. Jersey barriers are static and have a greater chance of causing injury.

City Manager Chad Bird said the bridge is considered “fracture critical.”

“When one piece goes, the whole thing goes,” Bird said. “Just look at the exposure and liability if someone gets on there and the bridge goes down.”

Billups noted that if the bridge does fall down, it could destroy the sewer beneath it.

“I think we really have to protect the city on this,” Billups said.

Bird noted that the barrels would have further uses beyond protecting the bridge.

“For 12 grand, it seems like money well spent to protect us from a possible lawsuit,” Billups said.

Replacing the Cascade Bridge

The Cascade Bridge could possibly be replaced for roughly $7 million and is on the city council’s five-year plan. Ever rising inflation may drive the price higher over the next few years, though.

“I think this project is probably the biggest concern, from what happens with estimation and inflation and how you plan for this bridge. This is complicated work, and we don’t know how inflation will affect it,” Nick MacGregor said during an October council meeting.

A million-dollar grant from the federal government already obtained by the city is a good start, and other funds will be allocated as well. That includes more possible grants from national infrastructure projects.
The council will also be using part of the city’s $3.6 million in ARPA (American Rescue Plan Act) funds to pay for sewer separation – specifically the South Street sewer basin. That will free up debt capacity that can be used toward the Cascade Bridge, which means the city likely won’t have to issue a bond to pay for it.

Billups confirmed that the bridge will be a replacement of Cascade Bridge rather than a rehab of the existing structure, which dates back to 1896. The details will take shape in the coming months and years.

“The only thing for certain is that we are planning an all-traffic bridge that will have vehicles, bikes, and pedestrians,” Billups said.
