Drivers along Route 47 between Washington and St. Clair are about to get more say in how the highway of their daily headaches gets rebuilt. Missouri transportation officials are wrapping up a major conceptual study for the corridor and plan to return to the public with a tighter menu of options, updated cost estimates and a clearer picture of what gets built first.
The potential fixes range from relatively modest spot safety upgrades to full-blown intersection overhauls, and local leaders are already angling to move some of the bigger pieces to the front of the line.
According to The Missourian, MoDOT Franklin/Jefferson area liaison Jordan Dalaviras said the corridor study covers roughly 12.7 miles and carries an $87 million price tag as the agency finalizes its conceptual report. The Missourian also reports that consultants and project staff have already floated alternatives at earlier open houses, with more public engagement planned so residents can help winnow down the choices and set priorities.
What MoDOT Has Studied So Far
As outlined by the Missouri Department of Transportation, the Route 47 conceptual study runs from MO-100 in Washington down to I-44 in St. Clair. The work has leaned on online public surveys, stakeholder listening sessions and meetings of a Community Advisory Group that pulls in local perspectives from along the corridor.
MoDOT’s project page notes that consultants, including HNTB, have helped draft a range of alternatives. Those run from shoulder improvements and added turn lanes to potential multi-lane segments and larger intersection redesigns. The agency says it will post updated public materials once the team locks in its recommendations.
Locals Try To Jump-Start A Four-Lane Stretch
While MoDOT grinds through the planning details, some local officials are already pressing the gas pedal. Meeting summaries show the Washington Area Highway Transportation Committee has backed pursuing a MoDOT 50/50 cost-share program and federal Surface Transportation Program grants to speed up an initial four-lane extension south of Washington, according to Citizen Portal. That reporting also notes the committee expects additional Community Advisory Group meetings, followed by another public meeting where MoDOT will present more refined corridor alternatives.
Money, Timelines And Moving Targets
MoDOT’s own project materials put Statewide Transportation Improvement Program funding for the Route 47 work in the mid-$70 million range, with fiscal 2028 currently listed as the anticipated start of construction, according to a MoDOT project newsletter. Those mid-$70 million STIP figures sit below the $87 million estimate given to The Missourian, a gap that underscores how costs will keep shifting as designs are refined and right-of-way needs become clearer.
Officials say a mix of STIP funding, local cost-share contributions and federal grants is expected to be on the table to cover different pieces of the project.
What Residents Can Expect At The Next Meetings
When MoDOT returns for its next round of Route 47 meetings, staff plan to roll out a more detailed look at what the rebuilt highway could actually feel like. According to Citizen Portal, the team is preparing refined cross-section options that could include two lanes with improved shoulders, three-lane stretches or four-lane segments, along with intersection concepts such as diverging diamonds and continuous-flow intersections near the Route 47 and US-50 area.
Project presenters have been stressing the tradeoffs: more lanes and bigger intersections may cut travel times and reduce crashes, but they typically come with higher costs and wider right-of-way impacts. Smaller-footprint safety fixes, on the other hand, can be cheaper and less disruptive, but might not deliver the same congestion relief. Expect displays that spell out those choices in plain terms and map out which sections are most likely to see construction first.
MoDOT says it will announce dates and materials for the next public meetings on the Route 47 project page and through local partners as the conceptual study wraps up. Residents can also reach out to project staff listed in MoDOT materials, including the project manager and the Franklin/Jefferson area liaison. Feedback at these upcoming sessions will help decide which segments move from concept to design and how the overall project gets phased.
