Administration consider I-676 to use the surface streets; the Pennsylvania Department of Transportation and the New Jersey Department of Transportation consider I-676 to be continuous across the Ben Franklin Bridge, even though the bridge, built in 1926, is not up to Interstate standards (Aerial photo). This does not specifically violate Interstate standards, however, as the two separated segments of I-676 are in different states. I-78 travels along a one-way pair of surface streets, 12th Street and 14th Street, in Jersey City, New Jersey, between the end of the New Jersey Turnpike Newark Bay Extension and the Holland Tunnel, which leads into New York City. Between the two aforementioned points are four signalized intersections. I-180 in Cheyenne, Wyoming, has no parts built to Interstate standard; in fact the interchange with I-80 is just a simple diamond interchange with two traffic lights on I-180. It is expressway-quality with a few grade separations, however (Map). I-81 near Alexandria, New York before the Thousand Islands Bridge across the Saint Lawrence River has intersections with an off-ramp leading from NY-12 and a service road connecting from the bridge toll station to a police department while also intersecting NY-12. I-585 near Spartanburg, South Carolina. There are three sets of traffic lights at the northern end where it meets I-85 at a simple diamond interchange; two for the two sets of ramps and an additional light just south of the interchange for a local road. The route is concurrent with US 176, which continues from both ends of I-585. I-587 in Kingston, New York has a traffic circle (with yield signs) at its northern terminus with the ramps leading to/from I-87. Minor at-grade intersections Several Interstates in rural areas of the U.S. have minor at-grade intersections (including median breaks) with farm access roads or authorized vehicle-only driveways used for highway maintenance or connection to nearby utility stations. This is usually due to the lack of an old highway, the need to provide access to property that was accessed via the road prior to its upgrade to an Interstate, and the high cost to construct an interchange for the small amount of traffic that would use such a connection or to build a frontage road parallel to the freeway to the nearest interchange. I-11 in Boulder City, Nevada has an at-grade intersection with authorized vehicle-only service road giving access to Buchanan Boulevard and the WAPA Mead substation. An
