ST. LOUIS (KSDK) - The Missouri Department of Transportation announced details to significant improvements it plans to make to state routes within the St. Louis area.
Major construction projects include: Interstate 64 at Tower Grove interchange, southbound I-270 widening, I-70 Blanchette Missouri River Bridge, I-64 Daniel Boone Missouri River Bridge, and Route 109 improvements.
I-64 at Tower Grove Interchange
New pavement between Newstead and Kingshighway will be put down, and the interstate between Sarah and Kingshighway will be replaced. Four bridges over I-64 will be replaced: Taylor, Newstead, Tower Grove, and Boyle.
During the construction, lanes will be narrowed and shifted in both directions of I-64 between Sarah and Kingshighway. There will be three lanes open from 5 a.m. until 7 p.m. Up to two of those lanes will be closed on weeknights and weekends.
Three full-interstate closures are planned to remove the bridges and replace utilities. The first closure will happen on the weekend of January 25.
Taylor and Newstead over I-64 will be closed Monday, January 21 through November 2013. Once these two reopen, Tower Grove and Boyle will be closed for three months.
This $18 million project should be complete by mid-2014.
I-270 southbound widening
One lane will be added to southbound I-270 from Dougherty Ferry Road to I-44. Lanes will be closed daily between Manchester Road and I-44 beginning in late February. The closures will happen during non-peak daytime hours.
Blasting and occasional interstate closures on weekdays will start this spring.
The project to widen both northbound and southbound I-270 will cost $12 million.
I-70 Blanchette Missouri River Bridge
The five lanes of I-10 are reduced to three lanes in each direction on the bridge to allow for rehabilitation work.
Drivers are encouraged to use alternate routes, such as Route 370 and Route 364.
This project should be complete by fall 2013 and will cost $64 million.
I-64 Daniel Boone Missouri River Bridge
The existing westbound bridge will be replaced, but motorists are allowed to continue using the existing two bridges during construction.
During off-peak hours and weekends there will be a few lane closures. In February there will be some midday closures of I-64 for rock blasting, and will last for a few weeks.
The bridge should open in late 2014. All construction should be complete by late 2015, and will cost $111 million.
Route 109 widening, resurfacing, and safety improvements
The City of Wildwood partnered with MoDOT for a jointly funded project to improve traffic on Route 109 between Clayton and Route 100.
This project will widen Route 109 to two lanes in each direction with a roundabout to Pond-Grover Loop Road and a roundabout at the westbound Route 100 intersection.
Resurfacing work will begin within the next few weeks from south of Route 100 to the Meramec River, and daily lane closures will occur during non-peak hours.
Construction for the project will begin in late summer/early fall 2014 and will cost $7 million.
