Two Highway 47 improvement projects scheduled this year will impact traffic between Warren and Franklin counties.
The Missouri Department of Transportation plans to build a new Highway 47 bridge over Lake Creek, just south of Highway 94 at Dutzow, and realign the section of Highway 47 at Hopewell Hill to eliminate sharp curves.
Both projects are scheduled to be constructed this year.
Erik Maninga, MoDOT area engineer for Warren County, said Monday that the Lake Creek bridge will be built in two phases. The first phase would involve constructing a new, 15-foot-wide lane. In the second phase, a new 12-foot-wide driving lane will be constructed.
The 15-foot lane will be wide enough to accommodate large farm equipment, Maninga told members of the Washington Area Highway Transportation Committee Monday.
That was a concern expressed by area farmers when plans for the new bridge were presented at an open house meeting to outline the project and address questions and concerns.
Temporary signals will be used to direct traffic during the project, but flaggers may be used during peak times if traffic gets too congested, Maninga said.
MoDOT is looking at a 60- to 70-day schedule to complete the new bridge, but plans to build in incentives for the contractor if work is completed sooner.
There will also be some temporary lane closures using flaggers before and after bridge construction to repair shoulders and resurface the Highway 47 and Highway 94 intersection. These closures will occur during nighttime hours.
The new bridge will feature a 40-foot-wide roadway with 12-foot lanes, 8-foot shoulders, and will be 138 feet long.
The existing bridge, built in 1933, is only 26 feet wide and 113 feet long.
Planners expect the bridge project to be completed by Oct. 1, 2014.
Work on realigning about six-tenths of a mile of Highway 47 at Hopewell will cost an estimated $3.3 million.
Plans call for two sharp S curves to be eliminated, and for 11-foot driving lanes with 4-foot shoulders to be constructed.
Maninga said the project will require closing the highway at that point for about 18 days between June 1 and Aug. 15.
During that time, traffic will be detoured around the work site via Routes O and M, he explained.
Committee members asked Maninga to schedule the closure to avoid the Washington Town and Country Fair which runs from Aug. 6-10 this year.
Maninga noted that the contract includes incentives to complete the project within 75 days, which is down from the original timetable of 110 days.
