Project Spotlights

I-29/Nebraska Avenue Interchange

I-29/Nebraska Avenue Interchange reconstruction began in fall 2020. This project includes rebuilding the existing, folded diamond interchange to meet current design standards and capacity needs. The reconstructed interchange will resemble the existing configuration with two loop ramps and two diagonal ramps north of Nebraska Avenue. Reconstruction will improve sight distances for drivers at the Nebraska Avenue intersection and add additional lanes on I-29.

Earthwork and detour paving were the primary focus of improvements at the I-29/Nebraska Avenue Interchange in 2020. Construction of the new northbound bridge over Nebraska Avenue was also started in 2020. Interstate 29 bridge construction will be the focus during 2021. The contractor will also complete grading and paving to accommodate future lanes on I-29.

I-29/I-480/West Broadway Interchange

In 2021, construction activities will impact a new area of Council Bluffs. Construction efforts will shift to the I-29/I-480/West Broadway System Interchange. This improvement project will address capacity needs, increase safety, and correct functional design issues. The project will provide direct access to West Broadway from I-29 via one-way frontage roads on each side of the interstate.

The Program team is coordinating with adjacent jurisdictions and developing an outreach strategy, for travelers, businesses and residents in the project area. In 2021, construction will be focused on building a system of frontage roads. Frontage roads will serve traffic needs in this area when I-29 is anticipated to be under construction in 2022.

Getting You There

Wayfinding

Clear, easy to understand signs and directions help drivers navigate the interstate system through the Council Bluffs metro. When the dual, divided freeway opened in 2019, the Program considered the feedback received on how signage could be enhanced to benefit the traveling public. In 2020, new signs and pavement markings that designated lanes were installed to help drivers and improve navigability within the dual, divided freeway system.

In areas where construction is complete, permanent lane markings were installed to help guide travelers safely through the area. Markings include high contrast “skip dashes” to enhance visibility and reflectivity during rain and snow events and glass beads that reflect light to make them more visible at night. The lane markings in Council Bluffs were also applied using a new epoxy paint system applied in grooves that Iowa DOT is using to increase the lifespan of the lane markings. This new method of marking roads isn’t simply geared towards today’s drivers. The wider and more visible paint markings will help current vehicles that are equipped with safety features like lane-keeping assist, but Iowa DOT is also planning for the future where these lines will help autonomous vehicles ‘see’ the road better.

Unprecedented Challenges

In March 2020, new protocols were quickly implemented, due to the COVID-19 pandemic, to protect the health and safety of all team members, including contractors. As a result of school closings and people working from home, commuter traffic volumes decreased by as much as 40%. This reduction in traffic allowed contractors to close more lanes and revise overnight closure times. This flexibility meant that construction projects already underway were able to continue and remain on schedule.

Since collaboration still needed to occur with contractors and stakeholders, we found ways to virtually hold these important meetings. We conducted our first completely online Traffic Incident Management meeting with area first responders and had a record-setting number in attendance. The meeting drew engagement from participants as far as Ames, Iowa, and Lincoln, Nebraska, as well as from the Omaha-Council Bluffs Metro area. Pre-bid, construction kick-off, and weekly coordination meetings with staff and contractors has occurred virtually as well. We also engaged with elected officials through a virtual presentation to inform them about on-going and upcoming construction.

The Iowa DOT and Council Bluffs Interstate System Improvement Program, like all Departments of Transportation, has experienced financial impacts related to COVID-19. Much of the DOT’s funding comes from taxes on fuel. With commuter traffic down, the Iowa DOT re-evaluated schedules and made adjustments to accommodate projected revenue shortfalls. As a result, the Nebraska Avenue and I-29/I-480/West Broadway projects were moved to the state fiscal year 2021. Additionally, the pandemic continues to impact material availability and has increased material and labor costs. In spite of these challenges, the Program remains well under the original $2 billion estimated budget.

Public Outreach

2020 Communications

Since 2014, the Program has provided informative, timely, and concise communications to stakeholders and the traveling public throughout the region. The public engagement approach capitalizes on opportunities that communicate the thoughtful planning and execution of taxpayer dollars. Program, traffic, and construction-related information is shared with the public through a variety of in-person and online platforms.

In 2020, much of the Program’s public outreach was provided virtually; through social media and other online tools. The Program’s annual elected official’s briefing was presented in an online format in May. Prior to construction activities near the I-29/Nebraska Avenue Interchange, the Program provided website and email updates as well as direct contact with impacted stakeholders and businesses in the area.
