We begin our search for Lincoln’s route through Woodford County, Illinois where the Washington-Metamora road enters Woodford County from Tazewell County. As Lincoln and the other men who rode the 8th Judicial Circuit made the rounds they left Springfield and headed North into Tazewell County. Tremont was the county seat until 1850 when it was moved to Pekin where it remains to this day. From Tremont or Pekin, the judge and lawyers of the 8th Judicial Circuit traveled North through Washington and into Metamora.
On the County line sits this 8th Judicial Circuit Marker.
And here is an image looking North towards Metamora.
This road was not hard to discover since it was already marked but considering it is a major thoroughfare in the county between two important cities is should come as no surprise that the road is still in use today.
