Modifies provisions relating to memorial highway designation requirements and costs

HB 841 modifies rules for naming bridges or highways to honor people or events on Missouri's state highway system. It requires petitioners to submit an application with a state legislator sponsor, 100 supporting signatures, and a fee (capped at the cost of constructing and maintaining the signs). Special exemptions apply for memorials honoring fallen law enforcement, military members, emergency personnel, or state employees. Designations last 20 years with renewal options, and the state must post biographical links for honorees online.
