Posted by Edwards! on Fri Sep 13 01:21:01 2013, in response to Re: Bellmouths and tunnel expansions, posted by 3-9 on Thu Sep 12 13:10:38 2013. Actually..the Second avenue subway was planned by the BOT in conjunction with the 6th avenue Houston st subway.\the 8th avenue subway...the Concourse..and Queens Blvd routes.It was also inter linked with lines that were also proposed,such as the 34th st route..the 10 avenue subway on the far west side,and the new routes proposed for the outer boro's. The 2nd ave station's design had the SAS running through the upper level Mezz..which also served as part of the SAS Houston street two platform station. The same set up is found at East Bway F line station,where the Worth st subway crosses over the lower level,except at this station,it was partially built. you would never know you were standing in the Worth St subway because the track bed was covered over..the tunnels were sealed off on each end. The tunnel box is incomplete..of course,as it is as long as the station is wide. there a minor tunnel segments built into the upper level 2nd avenue station on each side,while the space was left open due to cost[why this was done here,and not to other provisions is strange,but looking at how huge the Houston st lines express stations are,it's a no brainier as far as expenses go]. So,,there IS room after all..yet cut and cover would have been used to build out the station to completion. Todays SAS plan has the new route traveling UNDER the Houston line,as the routes profile has been changed to "deep level" construction to avoid a ton of leftover steel left over in the street from the LOMEX/CHRYSTIE ST tunnels. |
