State Route 154, also known as the Bangerter Highway, is a state route in the U.S. state of Utah. The road forms a major urban arterial and partial freeway through the Salt Lake City region, from Draper in the south to its interchange with Interstate 80 at the Salt Lake City airport. The road is characterized by the innovative intersection shapes. State Route 154 is 39 kilometers long.

Travel directions
Most of SR-154 runs north-south, except for the southernmost section, which runs east-west. SR-154 begins in Draper at a SPUI junction with Interstate 15 and ends at the Salt Lake City Airport at an interchange with Interstate 80. The road is mostly a 2×3 lane road with at-grade intersections. Numerous intersections are designed as continuous-flow intersection (CFI). In addition, the SR-154 crosses some grade-separated roads without connection, as well as some railway lines. There are some level connections. The connection to the State Route 201 freeway is a diverging diamond interchange. SR-154 has a high quality character through the western neighborhoods and suburbs of the Salt Lake City region.

History
In the 1960s, plans were made for a major road through the west valley in which Salt Lake City is located, this was named the West Valley Highway and would run parallel to Interstate 15. The road became a state route in 1989 and was numbered State Route 154. In 1993, the road was named after Governor Norman H. Bangerter (1933-2015). The road was built in phases, the last section being the south east-west section until I-15 opened on November 17, 1998. This also opened the SPUI connection to the I-15.
The Bangerter Highway is nationally known for its large-scale application of the continuous-flow intersection. No road in the United States has as many as the Bangerter Highway. The first CFI opened in 2007 at the intersection with SR-171. After that, a large number of intersections were transformed into CFI in a relatively short time between 2008 and 2012.
Later, the Bangerter Highway was transformed into a freeway, often with 2×3 lanes on a fairly tight profile due to its location in an already fully built-up area.
In October 2011, the connection to SR-201 was reconstructed into a diverging diamond interchange. This type of connection became very popular in many states after 2010. Around 2012-2013, a SPUI connection was also constructed with the SR-48 (W 7800 S). On July 16, 2015, a SPUI connection with Redwood Road (SR-68) opened at Riverton and on May 13, 2017 a grade separated connection opened at 600 W. This replaced traffic lights at 200 West, near the connection on I-15. This created a 5-kilometer freeway on the east-west section of the Bangerter Highway.
On August 14, 2015, it was decided to upgrade several intersections of the Bangerter Highway to dissimilar connections, these are 5400 S, 7000 S, 9000 S and 11400 S. Of these, the northern two intersections were a CFI. Construction started in January 2017, all connections were fully opened on November 19, 2018.
In 2018, it was announced that the intersections at 6200 South, 10400 South and 12600 South would be grade separated between April 2020 and May 2022. The intersection with 6200 South was originally a CFI. The three connections were put into operation in the week of May 19, 2022. This left only one level intersection on an 18-kilometer stretch, at 9800 South.
Future
The SR-154 has intersections that are widely spaced with no local yard connections. This makes the SR-154 suitable for phased conversion to a freeway, by replacing each intersection with a grade-separated connection. The connection with Redwood Road, opened in 2015, has been constructed with 2×3 lanes and a space reservation for 2×4 lanes.
Work should start in mid-2023 to make the intersections with 13400 South, 4700 South and 9800 South grade-separated.
Traffic intensities
The SR-154 is a busy road, with around 100,000 vehicles per day at some intersections.
The southern portion of the route around Riverton has between 35,000 and 45,000 vehicles per day. Along South Jordan and West Jordan, this is 45,000 to 51,000 vehicles per day, and 50,000 to 55,000 vehicles through West Valley City. The northern part is somewhat quieter with 20,000 to 30,000 vehicles per day.
