Plans are under way to overhaul the historic Lincoln-Herndon Law Offices site in downtown Springfield.

The project will include a working version of the 1840s Tinsley Dry Goods store. Seth Tinsley ran the store and rented office space upstairs to Abraham Lincoln and William Herndon for their legal practice.

About $1.2 million in state money to pay for the project comes from capital construction funds. State officials say a start date for construction hasn’t been set. The renovation also will include new windows, signs, mechanical system upgrades and making the building compliant with the Americans with Disabilities Act.
