Pennsylvania Crash Hot Spots: The Most Dangerous Roads and Intersections

Where Pennsylvania Traffic Deaths Happen

PennDOT counted 1,042 traffic deaths in 2025, the fewest since the state started keeping records in 1928 and down from 1,127 in 2024. Most of those deaths didn’t happen on interstates. State highways other than the interstates, the numbered routes and boulevards that run through nearly every town, accounted for 785 of them, about three in four. Pedestrian and motorcyclist deaths both fell, but bicyclist deaths rose from 19 to 28.

PennDOT first reported 1,047 deaths for 2025, then revised the total to 1,042 in August 2026 based on updated information. The breakdowns in its crash facts booklet weren’t revised, so the road type rows still add up to 1,047. When it announced the 2025 numbers, PennDOT said driver behavior is the leading factor in 83% of fatal crashes, and that deaths in aggressive driving crashes are up 31% since 2020.

Pennsylvania’s Highest-Risk Corridors

A handful of Pennsylvania roads come up in crash coverage again and again. Here’s what makes each one tricky, with figures from PennDOT, city governments and regional safety plans wherever they’ve been published.

1. Roosevelt Boulevard (U.S. 1): Broad Street to Bucks County

The Boulevard runs about 14 miles from Broad Street through North and Northeast Philadelphia to Bucks County, with inner express lanes, outer local lanes and crossovers between them that force quick decisions at speed. City figures count 45 fatal crashes on and within 100 feet of the Boulevard from July 2019 to June 2023, and the Boulevard accounted for about 8% of all traffic deaths in the city over that time.

Speed cameras went live in 2020, and by late 2023 the city credited them with about 36 lives saved, 95% fewer speeding violations, 21% fewer fatal and serious injury crashes and 50% fewer crashes involving people walking. PennDOT is rebuilding the crossovers at five spots between Cottman Avenue and Red Lion Road, some of which the city calls confusing and dangerous, with full construction scheduled to start in spring 2026. A larger 12-mile safety and transit project is set to begin construction in 2028.

2. Broad Street (Route 611): The Navy Yard to Old York Road

Broad Street runs straight through the middle of the city, from the Navy Yard past City Hall and Temple University to Olney and Old York Road. North Broad is wide and fast, and it’s busy with people walking to the subway and buses at stops like Olney. Between 2018 and 2022, PennDOT data showed 169 serious or fatal crashes and 165 speed-related crashes on Broad Street, WHYY reported.

By early July 2024, seven people had been killed on Broad that year, double the Boulevard’s count over the same stretch, according to city data. Speed cameras went live on Broad in fall 2025, and the city says 15 camera locations now cover the entire street. Broad is also part of Philadelphia’s High Injury Network, the 12% of city streets that account for 80% of traffic deaths and serious injuries, and the Vision Zero Action Plan 2030 calls for a capital plan to guide safety improvements on every mile of that network by 2030.

3. I-95 (Delaware Expressway): Betsy Ross Bridge to Cottman Avenue

I-95 follows the Delaware River through Philadelphia, and the stretch through Bridesburg, Wissinoming and Tacony is a constant mix of commuters, freight trucks and drivers jumping on and off at closely spaced exits. Betsy Ross Bridge traffic from New Jersey feeds in here, and rear-end and lane-change crashes are the everyday problem.

This is also where a tanker truck fire collapsed part of the highway at Cottman Avenue in June 2023. PennDOT reopened I-95 in 12 days and finished permanent repairs less than a year later.

4. Schuylkill Expressway (I-76): King of Prussia to Center City

Locals call it the Sure-Kill. Narrow lanes, short merges, missing shoulders and the Conshohocken Curve leave little room for error, and CBS Philadelphia reported that it carries about 130,000 vehicles a day on the 14-mile stretch between U.S. 422 in King of Prussia and U.S. 1 at City Avenue.

PennDOT installed variable speed limit signs on that stretch in 2021, so the limit moves between 55 mph and 35 mph depending on traffic and weather. In the five years before, it averaged 568 crashes a year. Afterward it averaged 444 a year, a 22% drop, according to PennDOT.

5. Blue Route (I-476): I-95 to the Turnpike

The Blue Route carries I-476 north from I-95 near Chester through Delaware County, past the Schuylkill near Conshohocken, to the Turnpike at Plymouth Meeting in Montgomery County.

Its three big interchanges, with I-95, I-76 and the Turnpike’s Mid-County Interchange, are where the weaving gets heavy. When traffic goes from highway speed to stopped in a few hundred feet, rear-end and sideswipe crashes follow.

6. Penn Lincoln Parkway (I-376): Pittsburgh’s Parkways East and West

In Pittsburgh, I-376 is just the Parkway. The Parkway West comes in from the airport through the Fort Pitt Tunnel, and the Parkway East heads out through the Squirrel Hill Tunnel toward Monroeville. Tunnel backups and short merges mean sudden braking at the portals.

City figures show 21 fatal crashes in Pittsburgh in 2024: 3 on interstates, 10 on state routes and 8 on city streets. The city’s High Injury Network covers just 10% of its roadways but had 70% of fatal crashes and 60% of serious injuries in 2023 and 2024. Beyond the city, Allegheny County’s new safety action plan counted 339 deaths and 1,757 serious injuries on county roads from 2019 to 2023, and named 10 priority corridors, including Ohio River Boulevard and Brownsville Road.

7. I-70: Washington County and the I-79 Overlap

In western Pennsylvania, I-70 runs from the West Virginia line through Washington to New Stanton, where it joins the Turnpike. Around the city of Washington it shares the road with I-79 for a few miles, so north-south and east-west traffic, a lot of it freight, weaves across the same lanes.

It’s one of the state’s older interstates, with hills, curves and short ramps that leave little room to merge. PennDOT has been rebuilding it in sections, so expect work zones too.

8. I-81: Hazleton to Scranton

I-81 climbs through coal country from Hazleton past Wilkes-Barre to Scranton, with long-haul trucks mixed in with local commuters the whole way. Steep grades, mountain fog and winter snow make it hard driving, and around Scranton exits like the Central Scranton Expressway add city traffic.

The Lackawanna/Luzerne MPO counted 87 fatal crashes and 312 serious injury crashes in Lackawanna County from 2019 to 2023. Its High Injury Network covers 108 miles, about 5% of the county’s roads, yet holds 53% of the county’s high-injury crashes. Our Scranton car accident guide has more on crashes in the city itself.

More High-Crash Locations Across Pennsylvania

The big corridors aren’t the whole story. City safety plans, PennDOT data and local reporting have put numbers on specific streets and intersections in Philadelphia, Pittsburgh, the Lehigh Valley and Scranton, and these are the ones with published figures.

Several of these are getting work. Pittsburgh started safety upgrades at the Lawrenceville intersections in fall 2024, including pedestrian islands at Penn and 39th. In 2025, Allentown applied for a $7 million federal grant for safety upgrades and a reconfiguration of the Tilghman Street and Union Boulevard corridor, and the Route 22 study, covering 23 miles from I-78 to Easton, has a final report due in November 2026.

How to Stay Safe on Pennsylvania’s Most Dangerous Roads

None of this means avoiding these roads. It means driving them knowing where the trouble is, whether you’re behind the wheel, on foot or on a bike.

For Drivers:

1. Watch the posted limit, not just the sign you remember: On the Schuylkill, the variable speed limit can drop to 35 mph when traffic backs up. On Roosevelt Boulevard and Broad Street, speed cameras ticket drivers who go too fast.
2. Pick your lane early: The Boulevard’s crossovers and the interchanges on I-95 and the Blue Route punish last-second moves. Know your exit a mile ahead.
3. Let aggressive drivers go: PennDOT says aggressive driving deaths are up 31% since 2020. Leave space and don’t engage.
4. Put the phone away: Pennsylvania now bans handheld phone use while driving, and one glance down on the Parkway or I-95 is enough to rear-end someone.
5. Slow down in work zones: PennDOT counted 12 work zone deaths in 2025. Merge early on rebuilt stretches like I-70 and watch for stopped traffic.

For Pedestrians:

1. Cross at signals: On wide roads like Roosevelt Boulevard and North Broad, crossing mid-block leaves drivers almost no time to react.
2. Make eye contact: Don’t assume a driver has seen you. Wait until the car has fully stopped before you step out.

For Cyclists:

1. Wear a helmet: Bicyclist deaths in Pennsylvania rose from 19 in 2024 to 28 in 2025, and PennDOT says half of those killed weren’t wearing one.
2. Be easy to see: Wear bright colors, run lights at night, and use hand signals on streets like Butler Street and Penn Avenue in Pittsburgh.
3. Watch intersections closely: Turning drivers often don’t see cyclists. Never assume a driver will yield.

General Tips:

1. Know your route: If your commute includes I-76, I-95 or the Parkway, build in time for delays and drive defensively.
2. Check the weather before a long drive: Fog, snow and steep grades on I-81 and I-70 can change conditions within a mile.
3. Stay on top of alerts: PennDOT’s 511PA or a navigation app will show crashes, closures and construction as they happen.

What to Do If You’re Injured in a Pennsylvania Car Accident

A bad crash on the Boulevard, the Schuylkill or I-81 can leave you hurt and unsure what to do first. The first hours and days matter, for your health and your wallet.

1. Call 911. Even if nobody seems badly hurt, get police to the scene. They’ll write the official crash report, which is what insurers go by. If anyone is seriously injured, ask for an ambulance.
2. Get checked out. Concussions and internal injuries don’t always show up right away. Go to the ER or urgent care, and follow up with your own doctor in the days after.
3. Document the scene if you can. If it’s safe, photograph the vehicles, the damage and the license plates, plus skid marks, signs, weather and road conditions. Get witnesses’ names and phone numbers, and swap insurance information with the other driver without admitting fault.
4. Be careful with adjusters. The other driver’s insurance company may call soon after the crash. You can politely decline a recorded statement until you have your crash report and understand your options.
5. Keep everything. Medical records, bills, repair estimates, missed work, and every letter or email from an insurer.

Which agency has your report depends on where you crashed. The Pennsylvania State Police patrol the Turnpike and cover the many towns without their own police force, while city and borough departments, like those in Philadelphia, Pittsburgh, Bethlehem and Scranton, handle crashes on their own streets. Our Pennsylvania crash report guide walks through getting a copy from each.
