Robert Thompson — Tue, 14 Feb 2012 03:36:08 +0000

The new I-70 Mississippi River Bridge in St. Louis, Missouri is moving along and getting noticed in the news. Here are a couple of (somewhat) recent articles:

The Republic (Columbus, Indiana) (01/29/2012)

St. Louis Business Journal (01/10/2012)

KMOX CBS (12/28/2011)

The New Mississippi River Bridge Project page maintained by MoDOT has links to all that is happening on the project.

You can get real-time updates of the construction from three web-cams at this link. As I type today, the site is covered in snow. Very beautiful, unless you are trying to build a bridge on time!

The project page also has photo galleries and other neat stuff.

stltoday.com has some albums with good photos, including this one.

Previous posts on this bridge project are here, including the world record O-Cell test!

The kcICON project in Kansas City has been completed six months ahead of schedule and within budget with all lanes and ramps being open on December 18th. Demolition has begun on the existing Paseo bridge. You can see some photos of the demolition (like the one in this post – thanks kcICON!) at their Facebook page. It was a great experience for us to have been a part of this project. If you want to see all of our previous posts on this, click here. Other points of interest are linked below.

The Spring 2010 issue of Deep Foundations from the Deep Foundations Institute includes an article by Dan and Paul (with a little help from yours truly!). The article is based on our paper presented by Dan at the 34th DFI Conference on Deep Foundations last October in Kansas City.

The kcICON project continues to roll along. Check out their Facebook page where they have lots of photos and links to their YouTube page. They recently completed the widest bridge deck pour ever for MoDOT.

DBA on successful St. Louis Bridge team

DBA is on the successful team that was awarded the contract for the new Mississippi River Bridge in St. Louis, Missouri. The project is a joint project of MoDOT/IDOT with MoDOT being the lead agency. HNTB is the lead bridge designer for the new cable-stayed bridge carrying I-70 over the river. The bridge is one part of a larger project that also includes the Missouri North I-70 Interchange, the Illinois I-70 Connection, and the Illinois Tri-level Exchange.

From the project web site:

The $640 million Mississippi River Bridge project is proceeding through design, with construction scheduled to start in early 2010. The new Mississippi River Bridge is the first bridge built connecting downtown St. Louis and southwestern Illinois in more than 40 years. Currently, the only urban interstate bridge between Illinois and Missouri is the Poplar Street Bridge, known locally as the PSB. The PSB is one of two bridges in the United States that carry three interstates. By relocating one interstate (I-70) from the Poplar Street Bridge to the new Mississippi River Bridge, drivers will experience less congestion, fewer crashes and less unnecessary fuel use.

The new Mississippi River Bridge will be a 1,500 foot cable-stayed bridge across the Mississippi River between Metro East and St. Louis, Missouri. The bridge is two lanes in each direction, but is wide enough to be restriped for three lanes in each direction if traffic volumes warrant and additional funding is secured. In addition, the bridge project includes approaches on the Illinois and Missouri sides to get traffic to the bridge.

The wining contractor team is Massman/Traylor Brothers/Alberici Constructors. DBA’s role was to help prepare an alternate concept for the drilled shaft foundation design which will include load test measurements. We anticipate construction to begin in March with load test shaft.
