The 405 / 101 Interchange: A Gridlock Emergency

 
 

It is disappointing indeed that CalTrans will need seven years to complete improvements to the 101/405 interchange.  This interchange was built on the cheap in 1956 and desperately needs to be upgraded to handle today’s traffic.  As is, traffic spills off the 101 and 405 freeways and onto surface streets to make the transition, instead of using the gridlocked interchange.  This causes the local roads to congest, which in turn makes it very difficult for residents to access city amenities near the interchange.  If these much-needed improvements are not completed quickly, the communities around the interchange will continue to suffer.

Efforts are currently underway to improve the 101/405 interchange, but they are hampered by bureaucratic red tape that slows CalTrans down and prevents them from doing their job.  For example, the new lane under construction on the northbound 405 between Mulholland Drive and Ventura Boulevard has been funded since 1999.  This lane could have been completed in 2000, but CalTrans was required to do extensive studies and environmental impact reports to see if the narrow strip of land between the freeway and the abutting rock face was environmentally sensitive.  It is obvious to any driver stuck in traffic that the twelve-foot strip of land next to the 405 is not habitat land or wetlands, but regulations require that lengthy studies of the land be done anyway.  The result is that this needed freeway improvement has been delayed by several years.

Improvements have also been hampered by the MTA’s refusal to dedicate any significant amount of funding to this interchange.  The projects that are currently funded are a step in the right direction, but only drops in the bucket compared to what is needed.  The existing interchange has tight loop ramps that force drivers to slow down to 25 miles per hour, creating frictional slowing that causes long lines of cars to form as drivers wait to make the transition from the westbound 101 to the southbound 405.  Two of the interchange’s transition ramps deposit drivers from the 405 onto the left side of the 101, a dangerous configuration.  The interchange worked well in 1956, but not today.  It needs to be rebuilt and modernized, but government agencies are not cooperating with each other, and red tape is hampering any sincere efforts to improve the interchange.

It does not have to take seven years to build a freeway interchange.  After the 1994 Northridge earthquake, the Golden State/Antelope Valley Freeway interchange (5/14) was rebuilt in a few months.  The collapsed segment of the Santa Monica Freeway took only 66 days to rebuild, and that required the replacement of an entire viaduct!  Why did these projects happen so quickly?  The answer is simple:  Then-Governor Pete Wilson declared a state of emergency, which allowed CalTrans and private engineering firms to get to work immediately, to get the freeways up and running again.  In the absence of red tape, extreme environmental regulations, and other bureaucratic hurdles, construction agencies can do their jobs quickly and effectively.

The best solution to this bureaucratic mess is Senator Tom McClintock’s bill, SB 171.  This bill would give the governor the ability to declare a state of emergency when severe traffic congestion renders roads and highways impassable.  Like the 5/14 interchange after the Northridge earthquake, the 101/405 interchange is in a state of emergency--gridlock emergency.  It has been rendered essentially impassable by decades of neglect.  SB 171 would allow the governor to cut red tape and get the interchange upgraded quickly, so CalTrans and private engineering firms can get to work and traffic can begin to move again.
