The part of the frontage road that was deconstructed last year is fixed now, and you can go past Saltair and get to the Marina. The marina bathrooms are open all year (I think), and the Saltair bathrooms close for winter.

The little Falcon Guide Bicycling Salt Lake City shows that you can ride west on something called the "Airport Bike Path" from 2200 West, pass just south of (or through) the airport continuing west. We have looked for this, and I believe it is a mythological construct, possibly true in the past, but not now.

We drop in to the frontage road from 5600 West, having gotten there from California Street, although last time we were out there a month or so ago, the road was closed, and it was a festival of semi-trucks making dramatic U-turns. We joined them, and beat a hasty retreat back to the east.
