Starting today, for the next two months some east and westbound lanes of Interstate 70 will be closed from 6 p.m. to 7 a.m. The closures will extend from the Callaway and Montgomery county line east of Columbia to the I-70 and U.S. 63 interchange as part of the Missouri Department of Transportation program to upgrade safety on the interstate. Closures won’t involve more than one lane at a time in each direction.
The construction is a continuation of the guard cable installation project, tentatively scheduled to be completed in summer of 2005. It involves placing guard cables down the center of the interstate to stop crossover traffic and prevent serious crashes.
The transportation department has already installed concrete anchors for the cables along the median and is now creating a rock trench and weed barrier to keep vegetation down on the median, said Mike Dunavant, senior construction inspector for the department. Posts will be installed next spring, followed by the cable.
The median guard cable will eventually be statewide. After the current section is installed, I-70 will have continuous guard cables from St. Louis to Columbia.
“This is just step one,” said Roger Schwartze, district engineer for the department’s central area. “Next year we will bid a project from the west side of Columbia to Kansas City.”
Collins & Hermann Inc. of St. Louis was awarded the contract for the project for $3,053,160.
