What you are probably seeing on a map is an abandoned rail line that last ran approx 30 yrs ago. The rauils & ties have long been removed and at one point there was consideration into making this a jogging/bike trail. One thing to keep in mind about Lehigh Ave is that it is a one way street moving traffic into Woodbridge Ave. There is a popular diner at the corner of Lehigh and Woodbridge Av . Let me know if you have any more questions about the neighborhood.
