in both directions. The canyon road is open to private vehicles for a small fee on even calendar days and holidays, from Memorial Day weekend to the last day of September. Bicycles are allowed on odd calendar days during the summer, except holidays. Picnic sites are available via reservation. The canyon is closed to vehicles during the winter but is open to bicycles and pedestrians. Dogs are allowed in the canyon on-leash below the water treatment plant and watershed area, whose boundary is marked by signage near the four-mile marker. Crossings The only road crossing of the canyon north of Fourth Avenue (200 North) is the winding one-way Bonneville Boulevard. However, plans have been made for a more direct crossing. For instance, in 1916, the Salt Lake City Commission asked for bids for a proposed bridge at 11th Avenue. Later, as a World War II national defense project, a northerly bypass ("Bonneville Parkway") of downtown Salt Lake City was planned, connecting Fort Douglas with US-91 (now US-89) near North Salt Lake. The state legislature designated it to be State Route 231 in 1941, following 11th Avenue from the fort to a canyon crossing, and then curving north around Ensign Peak to North Salt Lake, but it was not built and was removed from the state highway system in 1945. (Other defense projects that were built include present SR-168, SR-193, and SR-232.)
