Dyer Avenue is a short, north-south thoroughfare in the Hell's Kitchen neighborhood of Manhattan in New York City, located between Ninth Avenue and Tenth Avenue. It is primarily used by traffic exiting the Lincoln Tunnel. Dyer Avenue runs between West 34th Street and West 42nd Street but functions as two distinct sections due to its connections with the south and center tubes of the Lincoln Tunnel. The at-grade portion of the Lincoln Tunnel Expressway between West 30th Street and West 31st Street is also referred to by street signs as "Dyer Avenue." The roadway is owned by the Port Authority of New York and New Jersey.
South of West 38th Street, Dyer Avenue is used by southbound vehicles exiting the south tube of the Lincoln Tunnel. Traffic exiting the center tube of the Lincoln Tunnel may also access Dyer Avenue by using an exit ramp from the Lincoln Tunnel Expressway that merges with Dyer Avenue before its intersection with West 36th Street. At this intersection, there is also a southbound entrance ramp to the Lincoln Tunnel Expressway. This ramp permits traffic from the south tube of the tunnel to access the expressway; however, the amount of traffic using this entrance ramp is relatively low because the Lincoln Tunnel Expressway ends a few blocks to the south at West 30th Street and was never connected to the proposed Mid-Manhattan Expressway.
Although Dyer Avenue is mainly used by vehicles exiting the Lincoln Tunnel, drivers entering the tunnel can travel northbound on Dyer Avenue for a brief segment between West 34th Street and West 36th Street. These vehicles merge with other vehicles from a loop ramp from Ninth Avenue that continues to the Lincoln Tunnel Expressway and provides access to the center and north tubes of the Lincoln Tunnel.
