I-15 Technology Corridor

Public Involvement and Support Services


I-15 between 14600 South in Bluffdale and Main Street in Lehi is a heavily trafficked area of I-15. Known as Silicon Slopes, this area of I-15 is the fastest growing area in Utah with a high number of technology-based businesses moving to this area every day. Development and growth have occurred more rapidly in this area than projected. Additionally, this section of I-15 was one of the last in Utah County to be rehabilitated. All of the I-15 bridges over surface streets had reached the end of their service life.

SJ+A provided communications support to Ames-Wadsworth, the Design-Builder for this award-winning Utah Department of Transportation (UDOT) project that was designed to address growth and upgrade aging infrastructure by…
• Adding two additional travel lanes in each direction;
• Building a new bridge over I-15 at Triumph Boulevard;
• Creating one-way frontage roads between S.R. 92 and 2100 North;
• Redesigning and building new interchanges at S.R. 92 and 2100 North;
• Reconstructing bridges at cross streets and railroad crossings; and
• Building a new bike and pedestrian connections.

SJ+A worked closely with A-W and the UDOT Communications team to ensure that they are up to date on project progress and planned impacts. SJ+A assisted the UDOT communication team by providing real time construction information and access to the site so that they can implement the communication program. We also assisted A-W in direct stakeholder coordination for access and site restoration following work activities.

SJ+A also assisted in the proposal development phase by contributing ideas to improve mobility during and after construction. Some of our innovations included partnering with the Utah Transit Authority to fund a shuttle in the business park adjacent to S.R. 92. Intended to help reduce congestion during construction, our funding actually contributed to a new bus route connecting several business parks to the Lehi Frontrunner station. We also proposed and secured information kiosks to share project information with the public via several locations around the S.R. 92 interchange – at business and commercial locations. These kiosks linked to the project website and provide interactive tools to get the public engaged.

SJ+A worked closely with the project team to create and submit project award applications and this project won a number of awards, including the 2021 Utah ACEC Engineering Excellence Award, 2020 Utah AGC Transportation Project of the Year, and Utah Construction & Design Magazines 2020 Highway Project of the Year.

Bulldog Boulevard

Public Involvement and Support Services


Bulldog Boulevard is an important part of Provo City’s transportation network. Many different types of travelers use this road – cars, trucks, pedestrians, and bicyclists. It hosts a wonderful mix of businesses from restaurants and shopping to recreation, health care, and schools. This project converted one travel lane in each direction to a buffered bicycle lane, added center medians, improved sidewalks and added landscaping.

SJ+A provided public engagement services to Provo City from early concept outreach, where we asked the public for their feedback about converting a travel lane to a protected bicycle lane in each direction through completion of construction. Based on public feedback, the design was changed to include a new traffic signal at 400 West.

SR-9 Renewed; Rockville to Zion National Park

Public Involvement and Support Services



The Utah Department of Transportation renewed State Route 9 (Zion Park Boulevard) in Springdale, Utah from the town of Rockville to the main gates of Zion National Park. The project reconstructed the roadway and added a storm drain system, bicycle lanes and wider sidewalks. Utilities were replaced or upgraded and power was put underground through the main village area. Springdale Town is a close-knit community with a diverse population of residents and business owners. With over 4.3 Million visitors a year, it was critical for the project to maintain traffic flow and keep businesses accessible while reconstructing SR-9.

SJ+A provided public involvement services to UDOT throughout the design and construction of this project. Design began in March 2016 and in partnership with Lochner Engineering, SJ+A facilitated three formal open houses, six informal informational meetings and presentations, and a Community Working Group that met twice a quarter to advise the team on town needs and interests while also sharing information about UDOT’s design process with the community.

Daily Users


SJ+A provided Public Involvement services to Utah County Constructors on  UDOT’s The Point project.

This project added lanes and rebuilt portions of I-15 in each direction from S.R. 92 to 12300 South, creating 6 lanes in each direction. The project also created a newly improved  interchange at 14600 South in Bluffdale.

Throughout the duration of the project, which stretched over the 2015 and 2016 construction seasons, SJ+A communicated closely with on-corridor stakeholders to ensure that they were up to date on project progress and any concerns regarding construction were discussed and resolved. SJ+A assisted the UDOT Communication team by providing real time construction information and access to the site so that could develop and implement the communication program.

South Davis Improvement Project

Public Involvement, Event Planning and Support Services


SJ+A led the Communication Management and Public Involvement program for UDOT’s I-15 South Davis Improvements project. This project added Express Lanes in both directions on I-15 between I-215 in North Salt Lake and Park Lane in Farmington.

The SJ+A team developed the overarching strategic and media communications plans, coordinated with UDOT and Design-Builder W.W. Clyde team members. We also worked directly with affected businesses and residents to keep them informed and up to date about major reconstruction affecting their main routes, accesses, and property.

This project involved significant face-to-face coordination as well as an ongoing strategic media campaign to communicate with the wide variety of affected stakeholders.

Communication techniques including emails describing upcoming impacts were sent out to over 1800 recipients each week. On the ground communication also played an integral part of our work. Over 20,000 flyers were distributed through the life of the project.

700 East Safety Improvements Project

Public Involvement, Events, and Support Services


Since 2010, there have been nearly 600 accidents on 700 East in Sandy from 7400 South to 9400 South. The Utah Department of Transportation (UDOT) and Sandy City have partnered to repave this section of SR-71 and improve safety. The 700 East Safety Improvements project will add raised medians at current and future signalized intersections and bike lanes, as well as repave 700 East between 7400 South and 9400 South beginning in July or August 2017. Project features will increase safety for motorists, bicyclists and pedestrians by designating specific turn locations and thereby decreasing the number and severity of accidents mid-block.

  • Raised medians will be installed at current and future signalized intersections.
  • Bike lanes will provide a designated space for cyclists, increasing motorists’ awareness of where bikes are on the roadway.
  • On-street parking will be removed.

SJ+A has provided public involvement support to UDOT since the project Design began in Summer 2016. The addition of raised-medians was controversial for businesses, and the proposed changes in traffic patterns due to the medians also caused concern for residents in the area. SJ+A worked with UDOT and Sandy City to engage the public in conversations about how to reduce the high number of crashes in the area while maintaining acceptable access and traffic flow. This complex process resulted in a cooperative process whereby the project design was adapted and plans for future traffic studies and improvements have been made. SJ+A facilitated two formal open houses, developed and produced an educational video, met personally with affected stakeholders and created presentations for City Council.
