History
TheBeltParkwaywasconstructedinthe1940’sand1950’sbyRobertMosesandisconnectedtothe BQEat65thStreetinBrooklyn.ItrunsaroundBrooklynwitheithertheparkwayelevatedorthelocal streetselevatedateachcrossing.TheparkwaycrossesnumerouswaterinletsfromJamaicaBayandis crossedbyatleastfourtransitlinesoverhead.Manyoftheoverpassesandunderpasseshavestone claddingand/orstoneattachedtothestructuraloverpass.
Overtheyearssinceitopened,therehavebeennumerousstructuresthathavebeenworkedoneither byinͲhouseforces,componentrehabilitationorpartial/fullreplacements.TherecentworkontheBelt hasbroughtseveralstructuresuptofederallimitedaccesshighwaystandards.However,therearestill manystructuresthatarewhollysubͲstandardandthosewillbeviewedinthisstudy.
Thisstudyisconfinedtothelimitsfrom65thStreetinBrooklynandSunriseHighwayinQueens.Thereis alsoconsiderationgiventostoppingattheVanWyckExpresswayasthatwouldthenformaloopof limitedaccesstruckrouting.However,therearealsosomeintersectionissuesontheQueenslegthat poseseriousissuestotruckstransferringontotheNassauExpressway.
1. LaneWidth.
ThelanewidthonmuchoftheBeltParkwayis11foot.Thisisclearlylessthanthe12foot requiredontheInterstatesystemandtherearenoshouldersexceptinthelocationsofthe6 bridgesinthecurrentBeltprogram.Ifwetassume tha addingtherequiredshouldersis necessarythecostofthatalonecouldbeprohibitive.However,therearecertainlyportionsof theroadwaywherethiscouldtakeplace.
Assumingjusta12footwidelanewidthitwouldbepossibletoinstallalongtheentirelengthwe arelookingataddingthreefeetineachdirection.
Thatcostwouldberoughly$50millionplusdrainagerelocationsandusercostassociatedwith thisconstructionduetodelaysexperiencedbythetravellingpublic.
