Maryland Route 943, formerly Maryland Route 143, better known as "Warren Road", is a road running through the area of Cockeysville, Maryland.

Warren Road starts directly off I-83 as exit 18, accessible from the northbound direction only. The Warren Road Light Rail Stop is located in this area, and then Route 943 ends at Beaver Dam Rd. Warren Rd continues east as a County-maintained roadway followed by a major intersection with York Road. The section of the road from Beaver Dam Road to Ridgland Road is also part of the route of Maryland Transit Administration Bus Route 9.

Past this area is a truss bridge crossing of the Loch Raven Reservoir ( [http://maps.google.com/maps?f=q&hl=en&geocode=&q=Cockeysville,+MD+21030&ie=UTF8&ll=39.488505,-76.609442&spn=0.001913,0.003954&t=h&z=18 see satellite image] ). The road changes names to Merrymans Mill Road and ends at Jarrettsville Pike near Jacksonville.

Warren Road originally ran through the now defunct town of Warren, Maryland, which was a mill town on the Gunpowder Falls. The town flooded out in the 1920s with the enlargement of the Loch Raven Reservoir.
