A Series of Unfortunate Events: The Tappan Zee Bridge By Iva Dixit   The  collective  hum  of  rush-­‐hour  traffic  on  the  Tappan  Zee  Bridge  is  loudly  interrupted  by   the  fierce  screech  of  brakes.  Drivers,  with  families  in  tow,  alight  from  their  cars  to  crowd   along  the  sides,  jostling  to  get  a  clear  view  at  the  construction  in  the  middle  of  the  water  (a   phenomenon  that  distinctly  un-­‐amused  traffic  authorities  call  ‘rubbernecking’).  Massive   loads  from  towering  cranes  swing  ominously  over  the  Hudson  River.  Clusters  of  white   workboats  whirr  noisily  through  the  water,  pushing  along  giant  orange  barges  laden  with   maritime  construction  machinery.       This  is  the  scene  of  the  most  expensive  public  construction  project  ever  undertaken  in  the   history  of  New  York:  the  three  billion-­‐dollar  replacement  of  the  Tappan  Zee  Bridge,   commissioned  by  Governor  Andrew  Cuomo’s  administration.  The  rubberneckers’  curiosity   is  not  entirely  warranted,  given  the  possibility  that  these  same  vehicles  that  commute   across  the  bridge  everyday  and  pay  $5  as  toll,  might  be  the  ones  inadvertently  bearing  the   cost  of  the  billions  required  to  replace  it.       Spanning  one  of  the  widest  parts  of  the  Hudson  River,  the  3.1  mile  long  Tappan  Zee  Bridge   opened  on  December  15,  1955,  at  a  cost  of  $80.8  million  ($668  million  when  adjusted  for   inflation  today).    One  of  New  York  (and  America’s)  busiest  roadways,  connecting  Rockland   and  Westchester  Counties,  it  is  one  of  the  major  routes  for  passenger  cars  and  commercial   trucks  alike,  joining  New  York  with  New  England,  allowing  vehicles  to  skirt  New  York’s   gridlock.       Of  the  170,000  vehicles  that  cross  the  bridge  per  day  (compared  for  the  original  capacity  of   38,00  for  which  it  was  built),  few  are  aware  of  the  dogged  political  history  behind  its  odd   choice  of  location  at  Tarrytown,  the  second  widest  section  of  the  Hudson  after  Haverstraw   Bay.       Named  after  the  after  the  Tappan  Indian  tribe  and  the  Dutch  word  for  “sea”,  the  bridge  was   the  result  of  a  1950s  political  feud  between  Governor  Thomas  Dewey  and  the  Port   Authority.  The  latter  was  building  a  bridge  of  its  own  near  Dobbs  Ferry,  across  the  border  of   New  Jersey,  a  site  within  the  25-­‐mile  radius  around  the  Statue  of  Liberty  that  defined  its   area  of  operation.  Dewey  was  adamant  against  having  to  share  toll  revenue  with  New   Jersey,  wanting  to  reserve  it  exclusively  to  finance  the  Thruway.  This  spurred  his  decision  to   build  the  bridge  as  far  south  on  the  Hudson,  to  ensure  it  well  outside  the  jurisdiction  of  the   Port  Authority.       Decried  by  one  of  its  own  engineers  as  ‘one  of  the  ugliest  bridges  in  the  East’,  the  bridge’s   design  awkwardly  combines  a  large  cantilever  (the  ninth  largest  in  the  world)  to  give   leeway  to  ships  moving  in  the  east  side  of  the  Hudson,  with  a  mile-­‐long  flat  roadway  atop   concrete  piers.  Originally  built  to  last  50  healthy  years,  in  recent  years,  it  has  garnered   notoriety  for  shedding  chunks  of  concrete  with  such  alarming  regularity  that  the  water  can  

be  seen  in  from  the  holes  in  the  roadbed.  The  bridge  was  constructed  in  a  way  that  its   foundations  floated  in  the  Hudson  River,  employing  a  new,  untested  technology  that  saved   the  Thruway  Authority  millions  in  construction  costs.  While  the  buoyancy  reduced  the   number  of  deep  piles  that  needed  to  be  drilled  down  to  the  bedrock,  there  was  no  guarantee   of  their  durability  to  withstand  the  effects  in  case  of  a  major  seismic  event.       In  April  2000,  an  engineering  firm  Vollmer  Associates  released  a  comprehensive  three  year   long  study  of  the  Tappan  Zee  Bridge  and  the  I-­‐287  corridor  that  listed  a  series  of  structural   issues  of  the  bridge  that  were  in  need  of  dire  repair.  The  6-­‐inch  concrete  deck  continuing  on   from  1955  needed  to  be  upgraded  to  present  -­‐day  10-­‐inch  standards.  The  reserve  strength   of  the  bridge  was  weakened  by  the  increased  traffic,  making  its  already  structurally   deficient  foundation  further  prone  to  seismic  activity.  (The  report  estimated  that  an   earthquake  registering  between  M5.0  and  M6.0  could  cause  serious  damage  to  the  bridge,   particularly  on  the  causeway.)       According  to  a  2008  Environmental  Impact  Study,  all  rehabilitation  options  would  involve   substantial  modification  to  strengthen  the  structure;  similar  in  scale  to  the  effort  required   to  construct  a  new  bridge.  All  eight  of  the  bridge’s  floating  foundations  would  need  to  be   replaced,  and  the  piers  and  steelwork  would  need  to  be  strengthened.  For  the  rehabilitation   to  be  successful,  nearly  80  percent  of  the  bridge  would  have  to  be  rebuilt,  with  the  addition   of  a  new  supporting  partner  structure.       The  same  EIS  estimated  the  cost  of  rehabilitation  at  $1.3  billion,  nearly  identical  to  the  cost   of  replacement.  However,  rehabilitation  would  only  improve  the  Tappan  Zee’s  structural   condition  and  reduce  short-­‐term  maintenance  requirements,  without  addressing  the   bridge’s  lack  of  redundancy.  Moreover,  it  neither  increased  the  bridge’s  vehicular  capacity   nor  serve  mass  transit  needs.    Instead,  both  the  Vollmer  study  and  the  EIS  recommended  a   complete  replacement  of  the  existing  span  with  a  new  eight-­‐lane  bridge.  To  accommodate   the  estimated  growth  in  reverse  commuting,  the  bridge  would  have  four  permanent  lanes  in   each  direction.       Structurally  deficient  and  vulnerable  to  seismic  activity,  its  wooden  pilings  bored  into  by   shipworms  and  stretched  far  beyond  its  estimated  lifespan,  the  Tappan  Zee  Bridge  had  been   the  talking  point  for  nine  governors,  nearly  a  hundred  million  dollars  in  studies  and  no   actual  construction.  It  wasn’t  until  2011  that  Governor  Andrew  Cuomo  fast-­‐tracked  the   project,  with  construction  slated  to  begin  in  two  years.       “We  will  finally  build  a  new  the  Tappan  Zee  Bridge  —  because  15  years  of  planning  is  too   long,”  said  Cuomo  in  his  2012  State  of  the  State  address,  presenting  it  as  a  modern-­‐day  Erie   Canal  that  would  bring  a  huge  upsurge  of  jobs  in  the  Tarrytown  and  Nyack  area.         The  replacement  was  to  be  known  as  the  New  NY  Bridge,  with  eight  lanes  for  general  traffic,   four  emergency  lanes  and  one  commuter  bus  lane,  with  bike  and  pedestrian  paths  added.     The  Thruway  Authority  remained  confident  that  it  could  raise  finances  through  a   combination  of  federal  loans  from  the  Obama  administration  and  the  sale  of  private  bonds   backed  by  increased  tolls.  The  winning  bid  for  $3.1  billion  came  from  a  consortium  of  

construction  companies:  Fluor  Enterprises,  Inc.,  American  Bridge  Company,  Granite   Construction  Northeast,  Inc.  and  Traylor  Bros.,  Inc.,  collectively  known  as  the  Tappan  Zee   Constructors.       Construction  on  the  bridge  continues,  but  Cuomo’s  grand  undertaking  has  encountered  a   financial  quandary  which,  if  not  sorted  out,  could  transfer  the  increasing  costs  of  the  3-­‐ billion  project  onto  the  taxpayers  of  New  York  State,  with  the  possibility  of  tolls  rising  as   high  as  $14  for  a  one-­‐way.       Cuomo’s  application  for  a  loan  under  the  Transportation  Infrastructure  Finance  and   Innovation  Act  (TIFIA)  program  originally  sought  to  cover  49  percent  of  the  total  costs.     However,  at  a  Senate  hearing  in  July  2013,  after  testifying  before  the  Senate  Committee  on   Environment  and  Public  Works,  US  Transportation  Secretary  Anthony  Foxx  said  that  the   Thruway  Authority  could  only  expect  the  maximum  of  $1.3  billion,  reducing  the  original   request  down  to  33  percent  of  the  cost.  To  qualify  for  a  loan  under  the  TIFIA  program,  the   creditworthiness  of  the  applying  institution  is  subject  to  review.  In  July  2012,  a  report   released  by  the  State  Budget  Crisis  Task  Force  co-­‐chaired  by  former  Lt.  Gov.  Richard  Ravitch   and  former  Federal  Reserve  Chair  Paul  Volcker,  expressed  serious  doubts  about  the  credit-­‐ worthiness  of  the  Thruway  Authority  to  be  able  to  fund  the  project.  Since  then,  the  rising   debt  accumulated  by  the  Thruway  Authority  has  already  earned  it  a  ‘negative’  rating  by   Standard&Poor,  the  credit  rating  agency.      

 

 

While  the  Thruway  Authority  remains  distinctly  mum  on  the  subject,  the  possibility   remains  that  it  might  have  to  fund  the  bridge  through  conventional  loans  at  higher  interest  

rates.  For  the  average  driver  on  the  Interstate  287,  this  could  imply  increased  bridge  and   statewide  Thruway  tolls.            

 

In  a  report  titled  ‘A  Bridge  Too  Far’,  the  founding  Trustee  of  Tri-­‐State  Transportation   Campaign  and  a  transportation  policy  analyst,  Charles  Komanoff,  predicted  the  inevitability   of  toll  increases,  one  that  follows  a  peculiar  growth  trajectory.     “The  lower  the  growth,  the  fewer  the  trips  in  future  years,  and,  hence,  the  higher  the  toll  per   trip  to  pay  off  the  debt  service.  However,  there  will  be  toll  hikes  to  pay  for  the  rebuild.  The   greater  the  increases,  the  more  that  trip  volumes  will  shrink  below  their  natural  trajectory.   This  will  require  further  toll  increases  to  make  up  for  the  lower  volume.”   Unaware  of  the  financial  ambiguity  surrounding  it,  the  men  driving  the  cranes  on  the   Hudson  go  on  drilling  into  the  Tappan  Zee’s  pillars.  In  the  distinct  absence  of  a  clarification   by  the  Thruway  Authority  on  the  subject  of  toll  increases,  the  bridge,  quite  like  its   foundations,  continues  to  lie  suspended  amidst  a  cloud  of  indecision.
