When the Hillsborough Reformed Church at Millstone decided to build a new church building in 1828, Joachim Quick had an idea. He could use the timbers from the dismantled old church to build a covered bridge at Branchville.
The bridge was built using wooden pegs to hold the timbers together - no nails were used.
When the bridge was replaced by a concrete span in 1929, it was one of only two covered bridges left in New Jersey. The other one being the Green Sergeant's Covered Bridge in Delaware Township.
The Green Sergeant's Covered bridge is 84 feet long. By comparison, the two-span South Branch Covered Bridge was at least 50 feet longer.
The covered bridge was just north of where the new bridge crosses the South Branch. In the image above, you can see how the new approach from Branchburg Township angles slightly to the south to meet the new span, whereas the road to the covered bridge went straight across.
