ST. LOUIS (KMOV.com) – In 2013, the Missouri Department of Transportation plans to make significant improvements to state routes throughout the St. Louis metropolitan area.
In a press release, MoDOT said the improvements will include major renovations and upgrades to some of the busiest interstates and highways in the region.
Major construction work includes: Interstate 64 at Tower Grove interchange, southbound Interstate 270 widening, Interstate 70 Blanchette Missouri River Bridge, I-64 Daniel Boone Missouri River Bridge and Route 109 improvements.
“We are making some extensive improvements to our interstate system to help relieve some of the problem areas during motorists’ morning and evening commutes, which helps keep the roadways safer for residents and commuters traveling through the area,” said Ed Hassinger, MoDOT’s St. Louis District Engineer.
“We’ll be talking to residents and commuters throughout the area over the next few months to see what transportation improvements they feel are needed to keep them on the move," he added.
MoDOT outlined their planned work further below:
I-64 at Tower Grove Interchange
This project improves the interchange at Interstate 64 and Tower Grove, constructs new pavement between Newstead and Kingshighway, resurfaces the interstate between Sarah and Kingshighway, and replaces four bridges over the interstate.
During construction, I-64 will have narrowed and shifted lanes in both directions from Sarah to Kingshighway. Three lanes will be open weekdays from 5 a.m. to 7 p.m. On weeknights and weekends, crews will close up to two of those lanes, but will keep one open in each direction around the clock. There are three scheduled full interstate closures planned to remove the bridges over the interstate and replace utilities under the interstate. The first scheduled closure will occur on the weekend of January 25.
There will be long-term closures of roadways over the interstate as crews replace bridges. Taylor and Newstead over the interstate will be closed Monday, January 21 until November 2013. When Taylor and Newstead are complete, crews will close Tower Grove and Boyle for three months. Other work may require closures of the Vandeventer or Boyle ramps. This $18 million interchange improvement project is expected to be complete in mid-2014.
I-270 Southbound Widening
MoDOT will add one lane to southbound I-270 from Dougherty Ferry Road to I-44. Daily lane closures from Manchester Road to I-44 will begin in late February during non-peak daytime hours. Blasting work and periodic interstate closures on weekdays will start this spring. This project will help improve the flow of traffic between I-64 and I-44 during the evening commute. The entire widening project on both northbound and southbound I-270 is approximately $12 million.
I-70 Blanchette Missouri River Bridge
I-70 is currently reduced from five lanes in each direction to three lanes in each direction while crews perform a $64 million rehabilitation of the westbound bridge. Motorists are advised to use Route 370 and Route 364 as alternates especially during peak hours. Construction began in November 2012 and is expected to be complete in fall 2013.
I-64 Daniel Boone Missouri River Bridge
Construction begins this month on a new $111 million bridge to replace the existing westbound bridge. Motorists will use the existing two bridges while the new bridge is constructed. There will be minimal lane closures during off peak hours and a few weekends over the course of the three-year construction. Starting in February, there will be momentary midday closures of I-64 for rock blasting during weekdays. This work will only last a few weeks. Westbound I-64 lanes will be narrowed later this year, but the same number of lanes will be open for peak hours. The new bridge opens late 2014 with all construction complete in late 2015.
Route 109 Widening, Resurfacing and Safety Improvements
MoDOT and the City of Wildwood have partnered to come up with $7 million for a jointly funded project to improve the safety and flow of traffic along the portion of Route 109 from Clayton to Route 100. As part of the project, Route 109 will be widened to four lanes (two in each direction) from Route 100 to Clayton, with a roundabout to the Pond-Grover Loop Road and a roundabout at the westbound Route 100 intersection. This solution will help improve the flow of traffic and safety for these motorists.
The Route 109 joint project to widen the highway between Route 100 and Clayton, along with the two roundabouts, will begin construction in late summer/early fall 2014.
Resurfacing work begins in the next couple weeks from south of Route 100 to the Meramec River. Daily lane closures during non-peak hours (could be day or night) will be necessary. Please pay attention to flagging operations and work zone signs.
