<P> The northern tube , which carries westbound traffic , originates at Broome Street in Manhattan between Varick and Hudson Streets ; it continues to 14th Street east of Marin Boulevard in Jersey City . The southern tube , for eastbound traffic , originates at 12th Street east of Marin Boulevard , and surfaces at the Holland Tunnel Rotary in Manhattan . The entrance and exit ramps to and from each portal are lined with granite and are 30 feet ( 9.1 m ) wide . Although the two tubes ' underwater sections are parallel , the tubes ' portals on either side are located two blocks away from each other , in order to reduce congestion on each side . The Holland Tunnel 's tubes initially contained a road surface made of Belgian blocks and concrete , but this has since been replaced with asphalt in 1955 . Each tube contains a catwalk on its left ( inner ) side , raised 4 feet ( 1.2 m ) above the roadway . Five emergency - exit cross-passages connect the two tubes ' inner catwalks . When the Holland Tunnel opened , the catwalk was equipped with police booths and a telephone system , stationed at intervals of 250 feet ( 76 m ) . </P>
