Carroll Road Detours Cost Local Businesses Time and Money

Eight miles. That is the extra distance drivers must cover to cross the Big Gunpowder Falls on Carroll Road in northern Baltimore County since the bridge collapsed in October 2025.

The single-lane metal truss bridge, built in 1879, gave way after a tree fell on it and a septic truck drove over the compromised structure. The Baltimore County Police Department determined the truck was not at fault. No one was injured in the collapse.

The closure has forced residents to take a longer route, adding at least 20 minutes to daily trips. Fran Burns, 68, who lives on a horse farm north of the crossing, said she now combines errands to avoid the detour. She estimates her trips to Hunt Valley, which used to be quick, now take about 40 minutes.

The delay has also affected local commerce. Marcia Bryant, 68, manages Roseda Farm, a beef cattle operation just north of the bridge site. She said the closure has made it harder for customers to find the location. Some callers have told her they will not visit because the extra drive takes 25 minutes. Bryant noted that while regulars have adjusted, the flow of new customers has dropped.

County officials say the rebuilding process is complex. The Department of Public Works and Transportation received $830,000 in federal funding for the first phase of design. This covers structural, roadway, and traffic engineering, as well as environmental reviews. Spokesman Ron Snyder said the total cost of the project is estimated at around $5 million, requiring additional funding that the county must still secure.

Snyder stated that the project will take four years from design through construction. Construction is not expected to begin until at least 2030, with completion planned between summer 2030 and spring 2031. He explained that the timeline includes applying for funds, soliciting contractors, and reviewing environmental regulations. He said the department is working as quickly as possible.

A point of contention between residents and the county is the bridge's width. Current design codes specify a two-lane structure, which would allow vehicles to cross without weight restrictions. The county initially considered this option but has not finalized plans. Snyder said the county is considering all options after hearing community concerns and may seek a federal waiver to keep the bridge single-lane.

Residents prefer a single lane. Linda Woolf, 73, who lives near the old bridge, called the push for a two-lane design wasteful. She said the original bridge served the rural road well for over 100 years. At a town hall meeting in early September, Burns and other residents argued that a two-lane bridge would extend the construction timeline and increase traffic on the rural road.

Traffic data from the Maryland Department of Transportation shows the road was not heavily used. A study conducted in January 2020 recorded a peak of 303 northbound vehicles at 5 p.m. on a typical day. The average daily traffic count for the 0.10-mile stretch south of Monkton Road was 2,485 vehicles.

The detour has shifted traffic to Sparks Road, which Burns says has become more dangerous. She noted that left turns onto York Road from Sparks Road are now particularly difficult. The county has not yet decided on the final design, leaving drivers to navigate the eight-mile detour for the foreseeable future.
