In LA Traffic, Design Purity Outmaneuvers Common Sense
In July 2011, Caltrans contractors demolished the southern half of the  Mulholland Highway Bridge,
 which spans the busy Interstate I-405 Freeway at  Sepulveda Pass in Los
 Angeles, California. The reasons for replacing only  one-half of the 
stately structure at a time are obscure. Suffice to say that  local 
homeowner groups held out for  purity of design.
 Rather than allowing the road to jog at either end of the  bridge, 
those groups forced Caltrans to build the same bridge twice, one-half  
each time. As they say, “Only  in Los Angeles…”
People
 who drive in Los Angeles know that “The 405” is the only freeway route 
 through the Santa Monica Mountains within twelve miles. Connecting the 
San  Fernando Valley with West Los Angeles, the I-405 is an 
ever-widening ribbon of  concrete, and one of the busiest highways in 
the world. In January 2012, I drove  southbound past the construction 
site to  Marina del Rey. My return trip that afternoon took me northbound over the  same route. 
On that morning, I timed my approach to the Sepulveda Pass for  10:00 
AM. With luck, the morning rush would be over, producing a lull before  
afternoon traffic built to yet another peak. All went well until  I 
neared the intersection of I-405 and U.S. Hwy 101. There, traffic slowed
 to a  crawl and did not regain equilibrium for the next ten miles.
As
 I ascended the Santa Monica Mountain grade, traffic snapped and bucked 
like a  Chinese dragon. In terms of vehicular energy flow, it was 
equivalent to an acute myocardial infarction. As I approached the crest,
 I could see why our  traffic moved so listlessly. Appearing atop the 
hill since my last visit, two  enormous mobile cranes stood like 
sentries, one on either side of the freeway.  From my viewpoint, the 
cranes appeared to be twice the height of the 100-foot  tall bridge. The
 scene was so startling that traffic slowed to a crawl and then  stayed 
that way until I was well beyond the construction scene.
Based on traffic delays alone, the current replacement plan makes no 
economic  sense. Once this slow motion economic disaster is complete, 
Los Angelinos can  then look forward to doing it all over again. From 
the coming Carmageddon II,  right through construction and opening, 
those who drive in LA shall experience  traffic jam déjà vu all over 
again. With the uncountable hours wasted by drivers  sitting in traffic 
below, we hope that the hilltop locals who blocked the  single-phase 
project are happy now.
Thanks to the local “design  purity movement”, motorists will experience inconvenience for years to come.  I wonder what the  late Steve Jobs
 would think of this version of design purity. Unless he  personally 
owned a house with an unobstructed view of the finished bridge, I  doubt
 that he would have supported this cause.
As traffic loosened up, my vitriol for the Mulholland Drive locals faded from my  consciousness. Traffic broke free  near Wilshire Blvd.
 in West Los Angeles, and I sailed along at 65 mph. After  crossing 
under Interstate I-10 (the Santa Monica Freeway), I observed a complete 
 absence of vehicular traffic on northbound I-405. As I approached 
Venice Blvd.,  I witnessed the culmination of a California Highway 
Patrol traffic break on the  northbound side of the freeway. Led by an 
animal control van, two CHP cruisers and several  CHP motor officers 
sped away from a phalanx of stopped traffic that stretched  for miles 
into the distance.
Listening
 to a later radio traffic report, I learned that someone had called  to 
report  an injured cat on the freeway. For the sake of that feline and 
in honor of the  kind soul who reported it, perhaps 25,000 vehicles came
 to an extended halt on the  busiest freeway in Los Angeles. Upon 
entering an LA freeway, a small animal’s  chances of survival are almost
 nonexistent. I am an animal lover and have a pet  cat myself. Still, I 
hope that iPhone toting animal lovers do not report every  small animal 
that enters the roadway. If they insist on doing so, Los Angeles  
traffic may never move smoothly again.
On my return trip, later that day, I approached Sepulveda Pass from the 
south.  From there I could see the Mulholland Drive Bridge and its 
attendant cranes.  Silhouetted against the northern sky, the two cranes,
 new concrete bridge supports  and the remaining bridge deck manifested as art.
 It is a sight so awe-inspiring that  despite traveling uphill, many 
drivers involuntarily slam on their brakes. As  traffic-engineers know, 
if enough motorists hit their brakes, somewhere behind  them, traffic 
will stop. My morning traffic had stopped three or four miles  short of 
the dramatic hilltop scene. 
As
 witnessed by their reactions to car crashes and brush fires, LA 
motorists  have a perverse relationship with those who trail behind 
them. During such  events, the collective reaction is predictable. To 
themselves motorists say,  “I’ve been delayed by the unknown and now I 
can see it, so I am going to slow  down and gawk to my heart’s content”.
 That day, of course,  group consciousness  among LA motorists was true to form.
My slow trips through Sepulveda Pass that day allowed me to see the 
sights.  If you hope to view this  high art sculpture for yourself, come
 to LA before  2016. If you miss the first round of bridge building, 
plan your visit for the  second round  in 2013 or 2014. Perhaps Caltrans
 can rejoin both halves of the new  Mulholland Drive Bridge by 2015. 
Then, hilltop homeowners can emerge from their  survival shelters and 
enjoy the purity of design that they forced upon us all.  Thank you 
again, local homeowners, for triggering the super slow motion 
Carmageddon that we now endure.
