context_page_description: Iowa Highway 99 was a state highway in southeastern Iowa. It began in downtown Burlington and generally followed the course of the Mississippi River north to Wapello. Most of the route was a part of the Great River Road. The highway was designated in 1931 and its course remained unchanged until it was removed from the primary highway system in 2003. It was replaced by County Road X99, though around Burlington, it is sometimes referred to as County Road 99.
context_section_description: Iowa 99 began at an interchange with US 34 in downtown Burlington, at the foot of the.  US 34 is an elevated highway that connects to the Great River Bridge and Iowa 99 passed beneath along Bluff Road.  Iowa 99 is joined by the Great River Road as well.  To the east of the highway lies a park and municipal marina, both of which abut the Mississippi River.  To the west, a bluff rises above the roadway.  North of Burlington, the highway followed the base of the tree-lined bluffs to the west; it served as a divider to the farm fields occupying the river bottoms to the east.  The road passed through the unincorporated community of Kingston.
  Near the Des Moines–Louisa county line, the bluffs recede to the west as the highway approached Oakville.  In Oakville, Iowa 99 turned to the west and crossed the Iowa River as the river bends to the north.  The road followed the western banks for a short way as the river approached its mouth at the Mississippi.  At Toolesboro, it turned to the northwest and passed the Toolesboro Mound Group, a group of Hopewellian burial mounds which date back approximately 2,000 years.  Shortly after Toolesboro, at County Road X61 (CR X61), the Great River Road turned away to the north.  Iowa 99 continued northeasterly until it reached Wapello.  There, it crossed the Iowa River again, albeit further upstream, passed through the town, and ended at US 61.
