SR 208 follows Block House Road north across the Po River, another Mattaponi tributary, and expands to a four-lane divided highway south of where SR 648 splits north on Block House Road. The state highway continues northeast and bypasses Spotsylvania Courthouse to the west. Just north of the county seat, SR 208 receives the other end of SR 208 Business (Courthouse Road) and passes the entrance to the Spotsylvania Courthouse unit of the Fredericksburg and Spotsylvania National Military Park. The state highway continues northeast as Courthouse Road, which crosses the Ni River, the northernmost Mattaponi tributary, and Massaponax Creek and passes through the suburban area southwest of Fredericksburg. SR 208 crosses over I-95 with no access before reaching its northern terminus at a four-leg intersection with US 1 (Jefferson Davis Highway) and US 1 Business (Lafayette Boulevard) at Four Mile Fork. The business route heads northeast into the independent city of Fredericksburg. US 1 connects SR 208 with I-95 and US 17 via an interchange between Four Mile Fork and Massaponax to the south.
