Next, US 29 encounters MD 32 at a symmetrical cloverleaf; for an extended period, this interchange marked the southern end of US 29's grade separation, with the entire route south of there being an at-grade expressway. North of the interchange, US 29 intersects several major routes that serve the community of Columbia: Shaker Drive/Seneca Drive, Broken Land Parkway, MD 175, and MD 108. Between Broken Land Parkway and MD 175, US 29 has a right-in/right-out interchange between the southbound carriageway and South Entrance Road; the northbound carriageway has an at-grade direct turnoff to Gates Lane (and formerly another turnoff to Old Columbia Road). Near the MD 108 interchange, the northbound carriageway has another direct turnoff to Diamondback Drive.
