![]() 5-1-1 is a great resource!ĭon’t forget that most states have a 5-1-1 system. In addition to winter weather travel reports and road closures, you’ll also be able to see construction delays, lane closures, chain law status, and possible detours. George Shillcock is the Press-Citizen's local government and development reporter covering Iowa City and Johnson County.Here are the interstate road conditions listed by state. "It definitely will be a lot easier of a transition (for bikers and pedestrians)," he said. Hayworth touted this part of the project, saying the overpass and tunnels will be a "key piece" of the project as the city sees more pedestrians and bikes cross the highway at this interchange. The trail first tunnels under the interchange and then has an overpass bridge over the highway. Renderings of the multipurpose trail show it will mirror the designs of other paths that cross the highway at the exits for Dubuque and North Dodge Street in Iowa City. "My experience has been you get through it before you realize there was anything different about it," he said. Hayworth admitted there will likely be a learning curve for residents to get used to the interchange due to them being less common in Iowa, but as long as people pay attention and read the signs they will be fine. our own residents in Coralville will find it smoother and easier." "It will allow people who are visiting the community to get off the interstate easier but also. "That's another important consideration here, it's just purely a safety matter," Hayworth said. Nevada football game? Here's where you can find parking He said Coralville and its neighbors have seen a significant increase in traffic and more bottlenecks backing up cars on the interstate. Hayworth said the completion of this project and the large I-80/I-380 interchange project underway will alleviate traffic congestion. IDOT argues the current interchange, known as a standard diamond, does not meet the needs of projected traffic volumes due to growth in the Iowa City metro and the draw that nearby attractions like the Xtream Arena and Iowa River Landing could bring, especially during large events.Ī national study published in the Transportation Research Record found that, by eliminating places where vehicle paths merge or cross, a diverging diamond interchange virtually eliminates left-turn crashes and can reduce all crashes by 46%. One was recently completed in Ankeny in 2020. This type of interchange is not in use in many other places in Iowa. IDOT posted a video in 2019 to help explain how the interchange would work. Traffic signals would stop oncoming traffic when the crossover happens. By doing this, a driver turning left to get onto the highway won't have to cross traffic.

More work would be done in 2025 on landscaping. The project would also include reconstructing the multipurpose trail along 1st Avenue with a new pedestrian bridge. Later in construction, one lane and the shoulders will be closed for new median burial and reconstruction. On I-80, IDOT will need to close at least one lane and the inside shoulders on the three-lane interstate to build new median piers and footing construction. The completed project will have two through-lanes in each direction. Coralville helped pay for early design and to obtain the federal grant.ĭuring construction, 1st Avenue will maintain one through-lane on one bridge in each direction while the other bridge is demolished and a new one constructed, starting with the east side first. ![]() ![]() Department of Transportation grant, which will cover about half of the estimated cost. ![]() The project is being paid by IDOT with help of a U.S. Hayworth told the Press-Citizen that estimate takes into account inflationary pressures, and the budget should include its impacts on the current bidding climate. The project is estimated to cost $42 million, according to IDOT, but construction and fuel costs have often caused the price of infrastructure projects to skyrocket. ![]()
