California State Route 109

State Route 109 (SR 109) is a short, unsigned state highway in the U.S. state of California. It is the portion of University Avenue that runs between U.S. Route 101 and State Route 84 in East Palo Alto and Menlo Park. The route is unsigned; however, it is noted on some online maps.

Route description

SR 109 begins at U.S. Route 101 in East Palo Alto. It continues north, paralleling the city border with Menlo Park before entering Menlo Park and crossing a railroad. SR 109 passes by salt evaporators before terminating at SR 84 just west of the Dumbarton Bridge.

History

In April 1958, I-109 was proposed as a name for the route that is now Interstate 280. This proposal was rejected by AASHTO. The route was first defined as a California State Route in 1963 from Sunset Cliffs Boulevard to Interstate 5 in San Diego. In 1972 this route was deleted and was redefined in 1984 as a route in Palo Alto.

The segment in East Palo Alto between US 101 and Notre Dame Avenue remains in local control. Under Cal S&HC § 409 (b), the state will not take control over this section until Caltrans and the city determine that it is in an "acceptable state of repair".

Utah State Route 109

State Route 109 (or SR-109) is a state highway in the U.S. state of Utah. The route serves as an east–west connector in the city of Layton in Davis County.

Route description

The route starts at the intersection of SR-126 (Main Street) and Gentile Street in the historic section of Layton, close to the historic Utah Central Railroad and the current-day Union Pacific Railroad, as well as the Layton Frontrunner station. From here, the route travels east along Gentile Street, almost immediately crossing Interstate 15 via an overpass, after which it passes by the Layton city offices and Layton High School. From this point onwards, the route primarily passes by residential subdivisions, crossing Fort Lane and Fairfield Road, the two primary north–south roads in the area. Shortly after Fairfield, the route splits off from Gentile Street, becoming Oakhills Drive as it continues east-northeast, climbing into the foothills of the Wasatch Mountains, where it ends at the intersection with US-89.
