North Utah County Boulevard Roadway Project

SCI Signal Crews Hard at Work

Owner: Utah County & Cedar Hills City

General Contractor: Flatiron Construction Corporation

Project Manager: Ben Vigil


Utah County has begun a roadway project to widen North County Boulevard, also known as 4800 West, between SR-92 (Highland Highway) and Highway 89 (State Street). Construction began this summer on Phase I (SR-92 to Provo Reservoir Canal), with Phase II (Provo Reservoir Canal to Hwy 89) scheduled to start in the spring of 2011. The project team expects to complete Phase I, including work in front of Lone Peak High School by late November of this year.

The planned improvements will provide a consistent five-lane roadway that includes two travel lanes in each direction and a center median lane. The project aims to improve safety, north-south mobility, and emergency service and response time—including better access to American Fork Hospital

“There will be a [traffic] signal at 1100 East and 700 North, somewhere around the fall of 2011,” Spencer said. “It will be in the next phase of the North County Boulevard reconstruction.” That project is also expected to place traffic signals on 1100 East at 300 North and 50 South. With those lights, 1100 East is anticipated to carry more traffic than surrounding streets. That would probably decrease the amount of traffic on 900 East.

Another anticipated change is related to the opening of the Murdock Connector, which would run east and west. It is projected to open in 2011, Spencer said. With that, 700 North is expected to carry less traffic, since residents of Highland will not have to go that far south to get to sites like Lone Peak High School.

SCI is proud to be the signal contractor installing these traffic signals, the new HAWK pedestrian signal system and the ATMS conduits and fiber optic cabling to allow the intersections to be interconnected. We have been using a variety of different construction methods to install the more than 6500 LF of  2″ HDPE ATMS conduit. Our backhoe’s and track hoe’s have been hard at work open trenching for the placement of the conduit and where this method isn’t feasible, we’ve been using our horizontal directional drills.

Our signal crews will be installing a new type of pedestrian signal system at the intersetion of 4800 West and Cedar Hills Drive, near Lone Peak High School. The High-intensity Activated crossWalK or HAWK signaling system is a combination of a beacon flasher and traffic control signaling technique for marked pedestrian and bike trail crossings.

The HAWK was invented by the Tucson, AZ DOT.

Here’s a short video on the system.
