海外TECH	Engadget	Hitting the Books: How Los Angeles became a 'Freewaytopia'	https://www.engadget.com/hitting-the-books-freewaytopia-paul-haddad-santa-monica-press-153036975.html?src=rss	Hitting the Books How Los Angeles became a x Freewaytopia x Some miles of freeway snake through greater Los Angeles connecting its million residents from Sylmar in the north all the way down to the shores of San Pedro Since the opening of the Arroyo Seco Parkway in have proven vital to the region but their construction has not come without significant social costs ーneighborhoods razed residents displaced entire communities cleaved in twain by the sprawling transportation infrastructure In his latest book Freewaytopia How Freeways Shaped Los Angeles author Paul Haddad takes readers on a whirlwind tour through the history and lore of Los Angeles sprawling highway system In the excerpt below we take a look at the Harbor Freeway where the first live traffic updates via helicopter took place Santa Monica Press Santa Monica PressOver the next four years the Harbor Freeway began to coalesce Press alerts went out with each new off ramp as they came online Olympic Washington Slauson Almost all were accompanied by the kind of theatricality that defined the era One of the dedications featured a shapely model named Ann Bradford who wore a sash emblazoned with the words “Miss Freeway Link ーcertainly one of the clunkier female honorifics dreamed up by a Chamber of Commerce Even the freeway s old nemesis Kenneth Hahn couldn t resist attending the th Street opening At the ribbon cutting on September Hahn boasted that the freewayーnow stretching ten milesーwas already L A s second busiest after the Hollywood Freeway When it s completed he said it will carry more traffic than “any street highway or freeway in the world The Harbor Freeway s immense popularityーeven in unfinished formーdid come with some growing pains for motorists The Downtown section proved to be a confusing lattice of bridges and ramps that required quick lane changes and sudden start stops As anyone who has merged from the Hollywood Freeway onto the southbound Harbor Freeway can attest the maneuver requires a “Frogger like thread of the needle through three lanes of traffic within a quarter of a mile lest you find yourself involuntarily exiting one of the Downtown ramps The nerve racking exercise is compounded by incoming motorists from the Arroyo Seco crossing the same three lanes from the other directionーleft to rightーwho are seeking the very exits you re trying to avoid Pulling off either move is nothing less than a navigational baptism for newbie drivers Some drivers can t pull it off at all Such was the case for Greg Morton a thirty four year old management consultant whose ordeal made him briefly famous In March of just south of the Four Level Morton attempted to weave to the right from the fast lane Suddenly a car veered into his lane and Morton panicked He wedged the wheel leftward and found himself marooned on the center median which in those days was simply a raised concrete strip with planters spaced every twenty feet These planters posed a problem for Morton He didn t feel he could get a “running start to rejoin the stream of whizzing cars So he waited for a break in traffic And waited And waited As he was stranded he tried to flag down eighteen passing police vehicles for help Only one stopped “You got yourself up there didn t you the officer chided “Just start your engine and drive off Which is exactly what the cop did Things got so bad Morton finally said to hell with it He took a beach towel out of his trunk and started to sunbathe right there on the median Perhaps this odd spectacle is what finally made a Good Samaritan assist this clearly delirious individual The stranger was a civilian on a motorcycle who promised to make a call from a phone booth for help Sure enough a sympathetic officer arrived within minutes and stopped traffic long enough for Morton to escape the median All told the Highland Park resident had been stranded for an hour and fifteen minutes When asked about it later Morton was shaken but took it all in stride “I d have given twenty bucks if as there should be there d been a telephone out there I could ve used to summon help he said Perhaps Kenneth Hahn was listening Four years later Hahnーby then a county supervisorーwas the driving force behind the installation of roadside call boxes Hahn posed for a photo at one placing an emergency call It was on the Harbor Freeway While call boxes would have to wait a few more years did see the first routine traffic reports from helicopters Prior to this freeway conditions were conducted by roving cars or sporadic airplane flights Radio station KABC was first out of the gate with Operation Airwatch Every weekday morning and afternoon traffic jockey Donn Reed delivered rush hour updates from the cockpit of a Bell whirlybird It was an instant hit with motorists and Reed had proof One morning he asked any drivers who saw his copter to flash their headlights Six out of ten cars did The fact that so many commuters tuned in may have saved the life of a three year old girl toddling through traffic on the Harbor Freeway Reed got his studio to cut into programming so he could warn drivers about her presence As cars slowed and paused she wandered off the thoroughfare no worse for the wear Not surprisingly the Harbor Freeway saw the bulk of traffic updates By more than vehicles per day were passing through The Stack That same year the Dodgers kicked off their inaugural season in Los Angeles after relocating from Brooklyn Home games were played at the Los Angeles Memorial Coliseum as the team awaited their permanent field in Chavez Ravine Built for the Olympics the Coliseum s football length field was not designed for baseball just as its dense Exposition Park neighborhood was not suited for battalions of cars jamming its streets from spring until fall Parking lots around the Coliseum could accommodate only vehicles forcing most motorists to pay to park on people s lawns or find street parking One fan from Phoenix who flew in to catch the game had to walk twenty four blocks afterward to find a taxi to his hotelーa longer journey than his plane ride Crushing traffic around the Coliseum backed up on the Harbor Freeway for a mile or more in each direction The delays led to a Dodger fan stereotype that persists to this day “Fans have been arriving as late as the third inning pointed out sportswriter Rob Shafer of the Pasadena Star News Mostly though Angelenos were so enamored by their Boys in Blue any inconveniences were met with wry wit “The one thing the Dodgers forgot to bring with them when they moved to Los Angeles was the New York subway quipped one newspaper When Liberace had the gall to perform at the neighboring Los Angeles Memorial Sports Arena during a Dodger game Rob Shafer swore that traffic on the Harbor Freeway created “some kind of human record for collective blood pressure	2021-10-09 15:30:36
