Debate continues over traffic on SF Great Hightway

SAN FRANCISCO - One week since San Francisco's Great Highway was closed to make way for a park, the closure remains controversial.
Now, both sides of the issue are looking to see how traffic patterns have changed since the closure.
The signs are clear that the southern portion of The Great Highway running along San Francisco's west side is now closed.
While the closure was controversial, now supporters and opponents of plans to transform the four-lane highway into a park are now debating how it will impact traffic.
On the Nextdoor app, some neighbors are complaining, saying traffic that should be on The Great Highway is instead speeding down residential streets.
"I've lived on La Playa since February of 1992," said Joe Baker, who lives just off the Great Highway and says the impact of the road's closure has been clear.
"That traffic now being diverted down La Playa Street and down lower Great Highway, those cars are running right through those stop signs," Baker said. "Those cars are not slowing down for speed bumps."
Supporters of The Great Highway say they have data backing up their position that traffic has settled into a similar flow seen before the pandemic, highlighting posts they gathered that say the traffic nightmare that some had predicted never materialized.
Catherine Unertl lives on 45th Avenue, just a few blocks from the Great Highway and said she's seen a modest increase in traffic.
"I think during rush hour, there's a little bit more traffic than would ordinarily be on the highway," said Unertl. "But, most of the day, it feels just like it did a week ago."
Commuters are learning to navigate the closure of The Great Highway.
KTVU watched as vehicles traveling northbound on The Great Highway turned onto Sloat Boulevard, and then made a U-turn to head north on The Lower Great Highway and 48th Avenue, which run parallel to The Great Highway.
Refugio Haro said before it closed, the Great Highway was his preferred route to get to work.
"With the Great Highway you used to go 35 miles per hour to get to one end to the other," said Haro. "It was a beautiful drive."
He takes the detour up 48th Avenue and says it has added a few minutes to his drive, but says overall it hasn't made a major impact on his morning commute.
"It's a little slower because of all the cars trying to figure out which way to go," said Haro.
People are still learning how to navigate around this closure, and traffic patterns are still developing.

New laws punish bad drivers with tech that forces cars to go the speed limit

New laws punish bad drivers with tech that forces cars to go the speed limit The technology aims to prevent vehicles from going over the speed limit. New laws lay out how the devices can be used to punish reckless driving. Show Caption Hide Caption San Francisco speed cameras busy snapping photos Speed cameras in San Francisco are busy at work taking pictures of drivers breaking traffic laws. Fox - Ktvu Beware, bad drivers: Some states are passing laws that punish reckless driving with devices that control vehicles' top speeds. Washington State recently became the second state in the U.S., joining Virginia, to enact a law placing speed-limiting technology in the cars of drivers with reckless driving records. Washington, D.C., also has a similar law. Washington Gov. Bob Ferguson signed a law in May requiring drivers whose licenses are suspended for reckless driving to have intelligent speed assistance (ISA) devices installed on their cars if they want to drive again immediately. The anti-speeding technology would monitor the driver's speed and prevent their vehicle from going over local speed limits. The law comes as Washington's state traffic safety commission reported that fatal crashes involving speeding drivers increased nearly 40% between 2019 and 2023. "This legislation was inspired by a crash when four individuals, including three children, were killed when their car was struck by a driver going 112 miles per hour," said Ferguson when signing Washington's new law. It will take effect in January 2029. The anti-speeding technology laws nationwide come as similar bills have been filed in at least five other states seeking to crack down on repeat reckless drivers, said Cathy Chase, president of Advocates for Highway and Auto Safety, a Washington, D.C.-based nonprofit. "Sometimes it just takes one state to get the momentum going," Chase told USA TODAY, noting traffic safety legislation is typically arduous. "This is a new type of measure with a newer technology in the U.S. that's really making good progress at the state level across the country." Virginia was the first US state to adopt an anti-speeding tech law In April, Virginia became the first state in the nation to enact anti-speeding tech legislation, requiring intelligent speed assistance devices for those convicted of driving more than 100 mph. The Intelligent Speed Assistance Program in Virginia is considered an alternative. The law allows judges to require intelligent speed assistance devices for drivers with repeat reckless driving offenses who don't want their license suspended. The devices are small enough to fit on an air vent and would stop drivers from exceeding the speed limit. Virginia's law has rules that are similar to the state's law on Breathalyzer ignition interlocks, said Tara Gill, a senior director of advocacy and state legislation for Advocates for Highway and Auto Safety. The Commission on the Virginia Alcohol Safety Action Program will oversee Virginia's ISA program, Gill added. Chase was encouraged to see the bipartisan support for Virginia's law that takes effect in July 2026. It was sponsored by Democratic state Del. Patrick Hope and signed into law by Republican Gov. Glenn Youngkin. "It's nice to see some common ground when our country can seem so divisive politically," Chase said. Meanwhile, lawmakers in other states have also considered some form of the anti-speeding technology requirement, including California and Connecticut, Gill said. And there are three states, Arizona, Georgia, and Maryland, where proposed ISA legislation is dead for the current session, Gill added. "We hope those states will reconsider those measures," Gill said. Reckless driving: Drunk driver caused fiery crash that killed 7 near Yellowstone National Park, police say Washington D.C. was first US municipality to pass reckless driving bill In 2024, Washington, D.C., passed the nation's first-ever legislation to enact Intelligent Speed Assistance for repeat speeding drivers. The reckless driving legislation in the Nation's Capital is called the ACT for 'Strengthening Traffic Enforcement, Education, and Responsibility '(STEER). The D.C. Council unanimously passed the measure. D.C. officials would be able to install "speed governors" on the cars of drivers convicted in court for aggravated driving or reckless aggravated driving. Meanwhile, New York City is expanding its ISA pilot program. A recent study involving 500 city fleet vehicles and over 2.9 million miles of driving showed ISA produced an 82% decrease on high-speed roads and a 64% decline in overall speeding. City officials say due to the pilot program's success, ISA is now being expanded to 2,100 vehicles. California has debated speed warnings in every car Meanwhile, California has mulled taking similar technology a step further, including a failed bill targeting every vehicle in the state. California's current ISA bill is stalled in the state assembly. Gov. Gavin Newsom vetoed a measure last year that would've made it the first such law in the U.S. The bill required that every new vehicle sold or leased in California in 2030 be equipped with a passive intelligent speed assistance system to alert drivers when they exceeded the speed limit by more than l0 mph. In his veto, Newsom said the National Highway Traffic Safety Administration (NHTSA) "already regulates vehicle safety standards, and adding California-specific requirements would create a patchwork of regulations that undermines this longstanding federal framework." Amid debate about the bill, the Alliance for Automotive Innovation, an auto industry lobbying association, questioned California's motives. The group referred to a 2022 law that requires new European vehicles have at least one of four speed limit recognition warning systems installed. "What they have in Europe is mandatory intelligent speed assist," the lobbyist group said. "It includes technology meant to be a reminder to the driver… not a restrictor… and uses cameras and GPS to recognize clear/visible speed limit signs on the roads."

CHP unveils new patrol cruisers designed to blend in with traffic

The Brief KTVU's Henry Lee got an exclusive first look at new CHP vehicles coming to Bay Area roadways. Three of these new Durangos will be coming to CHP offices in Hayward, Martinez and San Jose this week. CHP Commissioner Sean Duryee explained the cars have a "360-degree concealed" light package, making the cars harder to detect until the lights come on. WEST SACRAMENTO, Calif. - California drivers may hear – but not see – the new California Highway Patrol cruisers coming to several Bay Area cities this week. The new patrol cars, 400 of them, come in a range of colors with the goal of blending in with traffic. The CHP gave KTVU an exclusive first look at the agency's vehicles at the academy in West Sacramento, and how they'll assist in officers' apprehension of reckless drivers. CHP Commissioner Sean Duryee explained the cars have a "360-degree concealed" light package, making the cars harder to detect until the lights come on. "Drivers may be more familiar with CHP cruisers like these Dodge Chargers," Duryee said. "These are CHP cadets being trained at the academy's track. The [Dodge] Durangos are a different breed." The goal is to blend a bit more into traffic, Duryee said, allowing officers to apprehend dangerous drivers. Dig deeper Four-hundred of these new patrol vehicles will soon pop up across the state. Two-hundred of the cars will be black and white Durangos, 100 will be all white, and the remaining 100 cars will be a range of different colors, like "destroyer gray" and the darker "night moves" shade, Duryee said. With these new cars, the agency is looking to stand out less, compared to a typical police car. The patrol cars come with the regular components of a CHP cruiser, like dash cams, sirens and powerful engines designed for pursuits. Duryee took KTVU reporter Henry Lee out for a spin in the new cruiser. "How's the handling on this thing, compared to some of the other vehicles?" Lee asked. "It's actually really, really good, especially for an SUV. You really wouldn't expect that in an SUV," Duryee said. Three of these new Durangos will be coming to CHP offices in Hayward, Martinez and San Jose this week. Twelve others will be delivered across the Bay Area by the end of the summer.

Bridge repairs to begin after delay

Work to restore a 131-year-old bridge is due to begin following delays to the project. Built in 1894, the full refurbishment of the Causeway Bridge in Wolsingham was due to start last year but was delayed due to backlash from residents. The bridge across the River Wear will be temporarily closed to cars for three weeks from Tuesday, but remain open to pedestrians. The remainder of the project will be completed using temporary traffic lights, with a width limit of 3.25m and diversion routes in place. Durham County Council said the restoration is expected to be complete in early 2026. Follow BBC North East on X, Facebook, Nextdoor and Instagram.
