inconvenienced in downtown oakland or on shattuck ave in berkeley past or in the crossroads and figured all those bulldozers were just levelling another hillside for another freeway but whatever you've seen or bypassed or wonder about you've only seen a small part of a seventy five mile system now being built in three counties we want you to see some facts about your new in urban rapid transit system not just read about it so w keep quiet most of the time first let's take a look from the air the completed albany area structures part of the richmond berkeley mine the same type of aerials under construction  a section of the fremont oakland line and incidentally even as you watch this film all the construction you're looking at has progressed what you're seeing is how it looked the day we filmed and the day our cameras saw this was several months ago entrance to the downtown oakland subway now let's look more closely first getting ready for the transbay to linking oakland and san francisco which will enter the bay at the site of the oakland gold cross under the bridge and enter the market street subway under the ferry building the old san francisco wards dating back to the time or ferry boat commuting are removed to make way for high speed trains which will make the trip from oakland to san francisco in eight minutes the section is nudged to an outfitting dock where reinforced concrete is applied to the interior walls until its weight reaches twelve thousand tons more than a world war two liberty ship in the early morning hours when traffic main water tight and the process is repeated for the fifty seven sections and four long years while section after section of a tube is built to last bart's work progresses in more than a dozen cut and cover in downtown oakland for the subways moving utilities and sewers for the san francisco subway but one substantial contribution to the system is being made far enough from your front door  and the final large range undergoes processing some automatic that been stored ready to be placed and barked subway closer to home and part of your surface ride around the crossroads these bulldozers were leveling a hillside for a new fre only relocated but white to accommodate far trains in the median strip it's estimated that this portion of the conquered the berkeley line will save taxpayers millions of dollars because of the joint use of a narrow transportation c by bart and the california division of highways what about the route from a rented to berkeley over the hills where there is no transportation corridor even a narrow one the answer is through these hills we can fly from the east portal orinda side to the west portal in a few minutes it's taking two years to tunnel these hills but your bart train will make the trip in three one half minute charges for safety of both crews working so close together folded be a long nights or am much prove cleans up face from last blasts discouraging reports tunnelers have to install two more tunnel rings before another neatly open entire top of the face both crews move sharply to shore up ceiling and then after four hundred forty six days working opposite each other exchange places in their own type ceremony and meet in a modest ceremony deep in the berkeley hills marking the holding and when your bart train emerges from the berkeley hills tunnel it will blind long another medium strip that of a grove shafter freeway so called missing link in the bay area's highway system bart trains will enter the downtown oakland subway from the grove shafter freeway median and you will enter the same subway from southern alameda county at eighth and fallon street a few blocks from bart's headquarters building an automatic train control complex nerve center for the computerized seventy five mile network work started on this subway in late fall nine hundred sixty five a year ago this section of the subway had progressed this far really aerials really look like completed in landscape like this before and one half mile test track between concord and walnut creek we can't show you the market street subway yet but if you don't like temporary detours traffic jams and gaping holes wait construction of the downtown oakland subway makes a few detours seem like a picnic and berkeley pedestrians and motorists are already living with huge excavations as general manager be arse stokes told the commonwealth club in april one thousand nine hundred eighty seven the next two years or so will be years of tr of digging dirt of erecting steel pouring concrete i pledge that everyone associated with the district will do his level best to deliver the system to you as nearly on schedule as is humanly possible we've said that it will be the finest in the world we promise you it will be no less than that today more than half the seventy five mile system is under construction but tomorrow next month next year as heavy construction increases it will find more detours not fewer more blocked off traffic lanes and excavations all of which are necessary inconveniences but happily temporary so when you see this remember this daily reality of inconvenience is all part of getting ready getting ready to bring you the speed the safety but comfort convenience and the economy of the world's
