  • Five things to know about the I-70 Manchester Bridge project
    1. The morning commute on Interstate 70 could be a little more interesting in 2014 and 2015, but officials say replacing the Manchester bridge – two parrallel bridges, actually, from just west of the I-435 interchange over Manchester Trafficway, several rail lines and the Blue River – will disrupt traffic as little as possible. The three-lane bridges were built in the 1950s. The new bridges will each carry four lanes.
    2. The interstate’s overall configuration won’t change, and Manchester Trafficway will still be accessible from I-70. The project will cost $63.76 million. The Missouri Department of Transportation says one aim of the new constructon is to have lower maintenance costs in the long term.
    3. Construction begins in January 2014 and is to be done by Dec. 15, 2015. MoDOT promises to keep all three lanes of I-70 open in each direction during peak weekday traffic to minimize congestion. Lane closures will be at night and on weekends. There will be eight weekends when two lanes are closed, taking traffic down to one lane.
    4. The winning bidder, Clarkson/HNTB, was chosen in large part because of how its plans minimize traffic disruption. HNTB did a lot of similar work when the Grandview Triangle – formally called the 3-Trails Crossing Memorial Highway interchange – was rebuilt several years ago.
    5. The U.S. 40 bridge over the Blue River also will be replaced. That’s designed to improve access for trucks getting to and from the industrial area along the river. There will be shoulder and bike path for walkers and bicyclists as well. The bridge will be closed for 100 days for the replacement.
