A 75-year-old Severn woman died after a sport utility vehicle struck her while she crossed a busy county road Tuesday evening, marking the seventh fatal pedestrian incident in Anne Arundel County this year.
Darlene Platt was pronounced dead at the scene of the crash, which occurred at 6:55 p.m. on Oct. 21, 2025, along northbound Telegraph Road near Denson Drive. Anne Arundel County police said Platt had stepped eastbound from the median into the path of a 2022 Ford Bronco traveling in the No. 2 lane. The driver, a 45-year-old man from Glen Burnie, reported he did not see her until she was directly in front of the vehicle. The Bronco struck Platt before stopping.
Fire department personnel responded to the area, where they declared Platt dead. The county’s Traffic Safety Crash Reconstruction Team arrived to examine the scene and gather evidence. No charges have been filed against the driver, who sustained no injuries. Police continue to investigate factors such as visibility, road conditions and pedestrian movement.
An initial alert from the Western District described the pedestrian as unidentified and sought public tips to aid identification efforts. By Wednesday, authorities confirmed Platt’s identity through ongoing checks with family and records. Anyone with details on the crash is asked to call the Traffic Safety Section at 410-222-8573.
The incident unfolded on Maryland Route 170, a four-lane divided highway that serves as a key corridor through Severn, linking residential neighborhoods to commercial hubs and Interstate 97. Telegraph Road carries about 25,000 vehicles daily in the area, according to state transportation data, with peaks during evening rush hours when visibility drops with dusk. The stretch near Denson Drive features a grassy median but limited crosswalks, a design common on older state roads built for high-speed throughput rather than foot traffic.
This crash adds to a string of deadly collisions on the route. Just two weeks earlier, on Oct. 6, another 75-year-old woman, Linda Catherine Mierzeski of Gambrills, died in a head-on wreck on Telegraph Road in Severn when her vehicle crossed into oncoming traffic. Further back, a June 2021 two-vehicle crash on the same road near Buckingham Place claimed two lives after one car veered into the opposite lane. Such patterns have drawn scrutiny from safety advocates, who point to speeding, distracted driving and inadequate pedestrian accommodations as recurring issues.
Anne Arundel County’s pedestrian fatalities underscore broader vulnerabilities on local roadways. Through late October 2025, the county has recorded seven such deaths, part of 50 total traffic fatalities this year. That pace aligns with historical trends: From 2016 to 2020, the county averaged 10.8 pedestrian deaths annually, with 10 on state roads and one on local ones, according to the county’s Vision Zero analysis. Pedestrians made up a disproportionate share of the 234 traffic deaths and 1,311 serious injuries over that period, often at intersections or midblock crossings where drivers fail to yield.
Statewide, Maryland reported 382 traffic fatalities through Oct. 22, 2025, down slightly from 467 at the same point last year. Pedestrian deaths numbered 65 in the first nine months, contributing to a 25% rise in vulnerable road user fatalities since 2010. The Maryland Department of Transportation’s 2021-2025 Strategic Highway Safety Plan targets a drop to 98 pedestrian fatalities by year’s end, using an exponential decline from a 2005-2009 baseline of 106. Serious injuries aim for 364, reflecting efforts in engineering, enforcement and education.
Anne Arundel adopted its Vision Zero plan in July 2022, committing to halve pedestrian deaths to five by 2030 and reach zero by 2040 through the “six Es”: engagement, enforcement, engineering, emergency services, equity and evaluation. The framework prioritizes high-risk spots like state highways, where fatalities occur 10 times more often than on local roads. Contributing factors include unexpected crossings — as in Platt’s case — and speeds over 30 mph, which double fatality risks compared to 25 mph.
For Telegraph Road specifically, the county’s Region 3 transportation plan calls for capacity upgrades along MD 170 to ease congestion while incorporating bike and pedestrian links. Broader initiatives, like the Walk and Roll Anne Arundel program, push for continuous sidewalks, high-visibility crosswalks and traffic calming near residential zones. The Maryland Department of Transportation State Highway Administration has invested in similar projects countywide, including $6.8 million for pedestrian safety on MD 173 earlier this year.
County police emphasize prevention through awareness: Pedestrians should use designated crossings and wear reflective gear at dusk, while drivers must scan for movement in medians and reduce speeds in mixed-use areas. The Traffic Safety Section’s reconstruction work will inform potential recommendations, such as added signage or lighting at Denson Drive.
Platt’s death highlights the human cost of these gaps. Severn, with its growing population of 53,000, relies on roads like Telegraph for daily commutes, yet lacks the dense pedestrian networks of nearby Annapolis. As investigations wrap up, officials urge witnesses to come forward, underscoring how community input shapes safer designs.
