What is the timeline for the project and how can we get ongoing information about construction, detours and closures?
The I-270 North Project will run through 2023. During that time period, both MoDOT and the project contractor, Millstone Weber, will ensure that the public receives timely project updates throughout the course of the project. To get consistent updates by email we invite you to go to our project website at: http://www.i270north.org and sign up for ongoing project updates and information.
On our website you will also find current information about construction activities, detours and road closures, as well as Quick Links to final configuration plans, project photos and videos, and a project overview in both a video format and a Power Point presentation.
We also issue a monthly project newsletter that is distributed electronically to statewide and local elected officials, members of the Community Information Group, agencies and businesses who are working with us to distribute ongoing information to the community. Members of the public who have registered on our website to receive project updates or have expressed an interest via email also have access to the newsletter.
Why are Dunn and Pershall roads being converted to one-way?
Dunn Road and Pershall Road will be converted to one-way outer roads. Dunn Road will travel westbound as a one-way road starting east of the Old Halls Ferry interchange and ending at Hanley/Graham. Pershall will travel eastbound as a one-way road beginning at the Hanley/Graham interchange and ending at Old Halls Ferry. The one-way conversion creates an updated outer road system that allows for removal of all cross over slip ramps. The result will be improved safety and improved traffic flow throughout the corridor.
What are you doing to mitigate congestion with all of these closures and detours?
MoDOT and the project contractor, Millstone Weber, will provide access to timely project information for the duration of the project that will keep drivers informed of project activities so that they can receive consistent updates and plan routes of travel ahead of time. Visitors also are encouraged to sign up for project updates through our website at: www.i270north.org. The website will be the best source of information as it will be continually updated as changes occur. Visitors to the project website will find current information on construction activities, detours and road closures, as well as Quick Links to final configuration plans, project photos and videos, and a project overview in both a video format and a Power Point presentation.
In addition to the website, the project team issues a monthly project newsletter that is distributed electronically to statewide and local elected officials, members of the Community Information Group, agencies and businesses who are working with us to distribute ongoing information to the community. Members of the public who have registered on our website to receive project updates or have expressed an interest via email also will have access to the newsletter.
Lastly, each week the project team hosts a call that provides traffic updates for first responders, city engineers and school leaders. This call provides the details of every single traffic impact.
What is the I-270 NorthProject?
The I-270 North Project is the next step toward improvements along interstate 270 from I-70 on the west to the Chain of Rocks Bridge on the east. This follows the completed I-270 North Environmental Assessment (EA) that addressed impacts of congestion, safety, and mobility, as well as accessibility and aging infrastructure, along I-270. The Federal Highway Administration (FHWA) determined that the Preferred Alternative for the I-270 North EA will have no significant impact on the area. This means the Missouri Department of Transportation (MoDOT) can now move to the next step - upgrading I-270.
Why is this Project needed?
The project is needed because of the current issues on I-270, including outdated highway design, deteriorating infrastructure, and traffic congestion.
- Safety: I-270 North has a higher crash rate than comparable roads in our region. Some crashes can be attributed to traffic congestion, roadway geometrics, and vehicular travel speed differentials. Our project will improve mobility on the corridor and help reduce crashes related to traffic congestion. This project will make geometric improvements that address locations with high crash rates.
- Traffic Congestion: I-270 North is one of the heaviest travelled roads in Missouri. On average over 140,000 vehicles travel on I-270 North each day (Average Daily Traffic). I-270 North was constructed when traffic volumes were much lower. The I-270 North Project will improve mobility on the mainline, at the interchanges, and on the outer roads. This design build project aims to reduce traffic congestion faced by local users and interstate travelers.
- Deteriorating Infrastructure: I-270 is showing its age. Bridges and pavement are breaking down from many years of heavy freight volumes. Traffic signals, signing, drainage structures, and lighting are all deteriorating. The existing infrastructure is breaking down and resulting in emergency maintenance repairs. This project will address deteriorated infrastructure and ultimately will result in fewer work zones along I-270 for years to come.
Why is public involvement important to the project's success?
MoDOT is committed to meaningful stakeholder involvement and creating cost-effective transportation solutions that meet the community's needs. Reconstructing The I-270 North will be challenging from a construction phasing and maintenance of traffic standpoint. It is vital that the traveling public and the communities along I-270 North be involved and informed during development and implementation. MoDOT will keep residents, travelers, and businesses up-to-date on construction impacts and alternate routes for travel during the project.
