The cost to make lane and signal improvements at the Route V and Interstate 44 interchange at Rolla is under half a million dollars, according to the contractor awarded the bid for the project Tuesday.
The Missouri Highways and Transportation Commission awarded a $477,877.21 contract for the work to Lamke Trenching and Excavating, Inc., of Marthasville.
Lamke was the lowest out of five bids that were opened March 22. Lamke’s bid came in under the engineer’s estimated cost for the project, which was $582,155.
The other contractors that submitted bids were N.B. West Contracting Company, $547,325.13; Strait-Line Construction USA, Inc., $560,677.05; Don Schnieders Excavating Company, Inc., $562,316.93; and J.C. Industries, Inc., $578,769.34.
The interchange improvements as well as some additional work near Hy Point Boulevard north of the interchange is scheduled to be completed this summer.
According to design plans, the work will include widening both eastbound and westbound entrance ramps from I-44 to Route V at exit 189. This will allow for dedicated left-turn and right-turn lanes on each ramp. The plans also show a southbound right turn lane from Route V to westbound I-44.
The overpass will be restriped so that a center turn lane will be added for traffic traveling from Route V toward the westbound and eastbound exit ramps. The interchange also will receive updated signals with steel pole arms and a new controller at the ramp terminals.
Additionally, the plans call for widening Route V just north of Love’s Travel Stop for a dedicated northbound right-turn lane at Hy Point Boulevard.
“These improvements will make the interchange function and flow much better and make travel in the area safer,” said Preston Kramer, area engineer with the Missouri Department of Transportation (MoDOT).
The project is funded through a cost-share agreement between MoDOT and the City of Rolla.
