Eureka mayor: Allenton Bridge unsafe, replacement costs far exceed budget; city weighing $1M interim access via Legends Parkway

Eureka Mayor Sean told residents the Allenton Bridge was closed this year after a Missouri Department of Transportation safety inspection found it unsafe to carry traffic.

"It was deemed unsafe. It can't, it can't do anything," Mayor Sean said, describing the inspection result that prompted the immediate closure and the city’s limited authority to reopen the span.

The bridge has been on the city’s capital list for years. Voters approved Proposition E in early 2019 with a package of projects that included a roughly $6 million allocation for a bridge replacement, city hall and flood work. Since then the city has spent about $1.5 million on surveys, engineering and permit work; engineering estimates originally put a replacement in the $8–9 million range, but public bidding returned a low contractor price near $16.5 million and total project estimates that approached $18–20 million when ancillary contracts were included.

Why the escalation? Mayor Sean cited railroads’ work‑window policies and plan‑review requirements as a principal cost driver. Contractors factor repeated mobilizations into bids when Union Pacific and Burlington Northern will not provide predictable periods where crews can work over the tracks. The city also must secure multiple agency approvals, including MoDOT and railroad plan reviews, which added time and expense.

The funding picture remains uncertain. Mayor Sean said the city previously secured about $4 million in federal funding through a Transportation Improvement Program grant but remains short of the bid amounts. State Representative Holly Jones secured a $3 million line item in the House budget that was removed in the Senate, and that proposal is now back in committee with a low probability of passage, the mayor said. Mayor Sean said federal discretionary‑grant cycles the city expects to pursue typically open in December and close in February, which could delay construction until 2026 at the earliest and make a three‑ to four‑year schedule to reopening plausible even if additional funding is obtained.

Because the bridge replacement is unlikely to be completed quickly, the mayor presented an interim option: the city could accept and bring into the public road system a privately owned connector known as Legends Parkway, then put an asphalt overlay and other repairs on that road to create a second public access for neighborhoods behind the closed bridge. Public works estimates circulated on the call put that work at roughly $1 million; the city’s standard resurfacing approach uses existing concrete millings and an asphalt overlay, which staff said typically yields a 20–25 year service life in comparable subdivisions.

That option prompted sharp comment from residents of Ashton Woods and neighbors. Rebecca (resident) said she understood Legends residents had funds to fix their road but objected to the idea that the city would then assume long‑term ownership. "Wouldn't it also benefit them to put their money toward fixing the road and then it's opened up to be public?" she asked. Yancy (resident) supported adopting the parkway into the city system, citing emergency‑services access: "There’s a possibility we've got that way too," she said, arguing the second access could shorten emergency response routes when a train is blocking Main Street.

Several speakers stressed that a Legends Parkway fix is not a substitute for the Allenton Bridge. A group of Ashton Woods residents asked the mayor to continue pursuing state and federal funding for the bridge and to maintain pressure on private property owners and potential developers whose investments could help close the remaining funding gap. One resident said the bridge replacement was what voters approved under Proposition E and urged the city not to abandon that goal if it pursues the parkway option.

City officials noted tradeoffs. Mayor Sean said Prop E money and other municipal funds are fungible: money spent on one project reduces what is immediately available for others. He told the meeting the city has already issued $20 million in bonds for several Prop E projects and has drawn down funds across bridge design, flood contracts and a city building; he also noted a roughly $7 million flood contract supported by a $4 million grant and about $3 million in bond funds. Staff cautioned that if the city were to take Legends Parkway into its system, the cost of initial repairs and ongoing maintenance (snow removal, future resurfacing) would be borne by the citywide taxpayer base unless the parties negotiated a different cost‑sharing arrangement.

A number of residents suggested alternatives or additional actions: hiring a dedicated stakeholder coordinator to keep state and railroad talks moving, pursuing incremental repairs on Main Street between the tracks where feasible, and approaching businesses on Route 66 for potential local funding partnerships. Resident Brandon urged a dual track of work: continue efforts on the bridge while pursuing short‑term fixes, saying, "I don't think it's one or the other. I think we really could use all of the options ultimately." Resident Blake asked the mayor whether there was a drop‑dead date for the bridge project; the mayor said he expected about a year of clarity on whether additional funding or private development could close the gap.

Railroad approvals and federal protections for rail operations are recurring constraints. Mayor Sean described railroad plan‑review procedures, the use of third‑party managers by railroads (a vendor he called "Ganesh"), and the rail carriers' reluctance to guarantee work windows, all of which complicate construction sequencing and raise contractor mobilization costs.

What happened next: the trustees will consider the Legends Parkway option at an upcoming board meeting (the mayor referenced a May 6 meeting date), and the mayor said staff would circulate a poll or other outreach so affected residents can register their preference. There were no formal motions or votes recorded during the virtual Q&A session.

The mayor emphasized the city has been pursuing the bridge for years and said he sympathizes with residents' frustration: "I've spent a great deal of my time, and, I just truly wanted to avoid this situation." He added that the city will keep pursuing state and federal funding and asked affected residents to attend the trustees' public meetings to register support if they want the city to adopt the parkway or maintain focus on the bridge replacement.
