MoDOT Announces 2007's "Top 10 Work Zones To Look Out For"

JEFFERSON CITY - Travel season is right around the corner.  With Memorial Day coming up and schools closing for the summer, millions of motorists will soon hit the road.  But this year they'll discover numerous highway work zones and delays, because the Missouri Department of Transportation is in the middle of one of its largest-ever construction seasons, with well over 1,000 work zones active throughout the year.

"Missouri's roads are getting better in a big way this year," said MoDOT Director Pete Rahn.  "But that means there will be growing pains for the next few months.  We've got some big projects planned that will require motorists' full attention."

To help travelers prepare for what's ahead, MoDOT has put together a list of the state's top 10 work zones to look out for, based on volume of traffic, amount of work and level of delay.  "These are the projects most likely to slow you down, so avoid them if you can, especially during peak hours," Rahn said. 

The top 10 list of highway work zones to look out for in 2007 is ranked in order of impact.  Most work zones will not be active over the Memorial Day weekend, but it may be necessary for lane closures to remain in place.  For more information on these or other projects around the state, please call 888-ASK-MoDOT or visit http://www.modot.org/.

Top 10 Work Zones To Look Out For in 2007  

1. Kansas City - Triangle Project: Route 71 realignment and reconstruction - Route 71 will be reduced to one through lane at the I-435/I-470 interchange through the summer. Carries 70,000 vehicles per day. Major delays expected during peak hours, moderate delays during non-peak hours.

2. St. Louis - Eastbound Interstate 70 from Route 79 to Mid Rivers Mall Drive - Crews will add a lane from Route 79 to Mid Rivers Mall Drive. I-70 reduced to two lanes only going east. Construction runs May 2007- winter 2007. Carries 138,000 vehicles daily.  Expect major delays during morning peak traffic, moderate delays at other times.

3. St. Louis - Interstate 170 and Route 340 - A new interchange will be built at Route 340 and I-170. The construction reduces I-170 from three lanes to two in both directions and includes various ramp closures over the course of the project that continues until December 2007. Carries 101,000 vehicles daily. Expect major delays through peak travel times.

4. Springfield - Interstate 44 and Route 65 - This interchange will be reconfigured, including a new ramp for northbound-to-westbound traffic. Work scheduled summer 2006 through spring 2008.  I-44 carries 58,000 vehicles a day, and Route 65 carries 55,000 vehicles a day. Delays expected during peak travel times; traffic will be detoured onto state routes in town when bridges and lanes are closed at key points during the project.

5. Cooper County, west of Columbia - Interstate 70 from Saline County line to Route M - Lanes will be reduced eastbound for resurfacing.  Work will be completed in summer 2007.  Carries 28,000 vehicles a day.  Expect lane closures during the day.  The speed limit will be reduced through the work zone. 

6. Kansas City - Interstate 470 / Route 291 / Interstate 70 interchange - Resurfacing and bridge rehabilitation will close exit and entrance ramps in sequence through the early summer and lead to lane restrictions through the fall. Carries 50,000 northbound/southbound vehicles per day. Significant delays expected during peak hours.

7. Macon to Chillicothe - Route 36 - Four resurfacing projects are set for this 58-mile stretch across Macon, Linn and Livingston counties. Projects include 21 bridge rehabilitations, creating driving lanes as narrow as 10 feet over the course of the summer.  The projects also include upgrading two narrow sections of eastbound lanes near Brookfield and Meadville and widening outside shoulders in several locations. Projects will be completed this fall.  Carries nearly 11,000 vehicles a day. 

8. Cape Girardeau - Interstate 55 - While work on a new interchange continues north of town, northbound and southbound lanes are diverted to exit ramps between Cape Girardeau and Fruitland.  Work is ongoing to the end of the year.  Carries 9,500 vehicles daily.  Ten to 15-minute delays are possible.

9. Joplin - Business 71 (Range Line Road) and 20th Street - This intersection will be realigned, with turn lanes and sidewalks added. All work done during overnight hours from 7 p.m.-7 a.m.  Average traffic is 41,500 vehicles per day. Estimated completion date is Nov. 1.  Delays of up to 15 minutes at night.

10. St. Louis - Interstate 64 throughout St. Louis County and City - Initial construction work to rebuild I-64 is under way. Lanes on Interstate 170 reduced to two in each direction north from I-64 for one-half mile. Lanes on Kingshighway over I-64 will be reduced to two in each direction from June through December.  Additionally, other ramps and bridges will be closed throughout the year. Construction continues until summer 2010. Carries 158,000 vehicles per day. Expect delays through peak travel times.  Look for this project to be a chart-topper next year.
