Graded dirt began to give way to pavement earlier this month as construction continued on the third and final phase of Hwy. 364, also known as the Page extension.
A large concrete batching plant and paver have been at work since July 9 laying down the first 26-foot lanes on the final 9-mile leg of the extension. Page Constructors Joint Venture, a group of companies joined together as the major contractor for the project, began paving between Hwy. K and Interstate 64.
David Simmons, the project director for the Missouri Department of Transportation, said that paving will begin on the stretch between Hwy. K and Mid Rivers Mall Drive once paving is complete on the Hwy. K to I-64 stretch.
Some design changes also have altered the $118.9 million project.
Changing the proposed westbound Hwy. 364 exit to Bryan Road from a diamond interchange to a roundabout now means the extension project will open for traffic in two phases rather than three.
Simmons said the stretch of Hwy. 364 being built between Hwy. K and I-64 will open in early October – possibly as early as Oct. 3. The Hwy. K to Mid Rivers Mall Drive stretch is scheduled to be open by Oct. 31.
A frigid winter and wet weather prompted some construction delays of as much as a week. However, Simmons said Page Constructors now is making up for lost time and may be back on schedule soon.
Beyond paving, other construction work remains, including four bridges, an interchange and other improvements under various stages of construction.
The work includes additional ramps connecting Hwy. 94 and Mid Rivers Mall Drive to Hwy. 364. That work includes installing a bridge over Motherhead Road, a Gutermuth Road bridge over Hwy. 364, and bridges over Hwy. 364 at Hwy. K, and over Hanley and Henke roads.
Hwy. K will be widened to six lanes north and south of its new interchange with Hwy. 364. Other ongoing wor
k includes construction of a roundabout at Bryan Road and new ramps to complete the cloverleaf interchange at I-64.
MoDOT also announced a change last week that will affect traffic along the Hwy. 364 route. Beginning July 15, motorists from Mid Rivers Mall Drive no longer are able to go straight onto westbound Hwy. 94 from the far left lane of the North Outer Road. That lane has become a left-turn-only lane onto Mid Rivers Mall Drive. The middle lane still goes to westbound Hwy. 94.
The change was made because work crews are narrowing the ramp from Mid Rivers Mall Drive to work on its future c
onnection to Hwy. 364.
