and later crosses a bridge over Moniteau Creek. The highway enters Jamestown just as it curves to the west at South Mill Street (Route AA), then at the intersection with West Row Street joins up in a concurrency with Route 179. The two highways turn out of town back to the north and later the northwest. After the end of the concurrency with Route 179, Route 87 curves to the west. Between the intersections of two dirt roads, Homestead Road and Splice Creek Drive, it crosses the Moniteau–Cooper county line and enters Prairie Home. Shortly after the intersection with Route D, it turns northwest again, gradually curving toward the north after leaving that community and running through rural Cooper County. In Windsor Place, Route 87 encounters an interchange with Interstate 70 (I-70) and is joined by the east end of Interstate 70 Business (BL I-70), with which it has a concurrency towards the northwest, passing by a golf course. Sparse development can be seen along the way, and further northwest the road serves as the western terminus of Route 98, joining part of the Lewis and Clark Trail. Entering Boonville, the highway becomes known as Bingham Road, which has more suburban surroundings. The highway later makes a right turn at Route B and becomes Main Street. Over two blocks later, the highway is joined by US 40, Route 5, and the Santa Fe Trail, which is where BL I-70 makes a left turn. US 40/Route 5/Route 87 travels north along Main Street through historic downtown Boonville, and after the intersection with High Street, crosses the Boonslick Bridge over the Missouri River, crossing the Cooper–Howard county line, entering Franklin. Immediately after crossing the bridge, Route 87 leaves the concurrency with US 40 and Route 5 and turns left, taking the Santa Fe Trail with it. Route 87 and the Santa Fe Trail run in relative proximity to the north bank of the Missouri River crossing the Katy Trail State Park until just before the intersection with Howard County Road 339 (CR 339), and moves further away at the intersection with Route Z, which continues the previous trajectory towards Petersburg. From there, the road shifts at varying northwest angles. The road heads west-northwest as it enters Boonesboro and then has an overlap with Route J, which ends just after Route 87 makes a sharp right curve to the north. Well after leaving
