Future highway in South Dakota
South Dakota Highway 100 (SD 100) is the designation of a future state highway that will be built south and east of Interstate 229 (I-229) as a second southeastern bypass of Sioux Falls. The highway will run from exit 73 on I-29 east and north to exit 402 on I-90. This highway is currently named Veterans Parkway on its route from Interstate 90 to 57th Street in Sioux Falls.
Route description
SD 100 is expected to facilitate commercial and residential growth in the eastern section of the city of Sioux Falls. It will also serve as a second eastern bypass of the city, running roughly parallel to I-229 and about 2.5 miles (4.0 km) outside of it.
As proposed, SD 100 will begin at the single-point urban interchange (SPUI) at exit 73 along I-29 east of Tea. After crossing Tallgrass Avenue it will make a short northeast jog before turning east just before crossing Louise Avenue. It will start curving northeast just before meeting Western Avenue. This section from I-29 is anticipated for construction in spring 2024-fall 2025. Currently under construction beginning June 2023 is from Western Avenue, going northeast to an intersection with SD 115 (Minnesota Avenue), an overpass of 85th Street and an intersection with Cliff Avenue. The timeline for completion is fall 2024. The route is to continue northeast past this intersection until it is midway between 69th and 85th Streets; then the route will curve straight east with a bridge over the BNSF railroad to an intersection with Sycamore Avenue. Anticipation for the segment from Cliff Ave. is for design complete in summer 2024 and construction in spring 2025-fall 2026. After a short distance SD 100 is to bend to the northeast, where the road will meet SD 11, which will curve on a new alignment into an intersection which 69th Street will also be angled to. Both SD 11 and 100 will run together to the northeast until meeting 57th Street and cross going mainly north from Lincoln County into Minnehaha County. An SPUI is planned for 57th Street. This Segment 4 is anticipated for design completed in summer 2025 and construction in spring 2026-fall 2027.[1]
The Minnehaha County portion to I-90 is complete. After intersecting 57th Street, SD 100 (which is not yet signed) and SD 11 continue north to an intersection with SD 42 (Arrowhead Parkway). At this intersection, SD 11 leaves SD 100 and turns east along SD 42. Veterans Parkway continues north of this intersection until just south of Madison Street, where it curves slightly to the northeast. The highway continues northeast until intersecting a proposed extension of Benson Road at another SPUI. Here, the road turns northwest to intersect Rice Street and go on a bridge over a railroad, then back to the north before bridge crossing another railroad and the Big Sioux River and intersecting 60th Street North. Just north of 60th Street North, Veterans Pkwy. (planned to be SD 100) ends at what was previously a diamond interchange, but was upgraded to a SPUI, at exit 402 on I-90.[2]
History
Planning for a new southeastern bypass of Sioux Falls began in the 1990s, when community members collaborated with officials from the City of Sioux Falls and South Dakota Department of Transportation. Construction of the first segment of Highway 100, extending from just south of South Dakota Highway 42/Arrowhead Parkway southward to 26th Street. The rest of the eastern half of Highway 100, extending from 57th Street northward to Interstate 90, was constructed in phases over ten years. The last segment of this stretch, extending from Rice Street across the Big Sioux River to Interstate 90, opened to traffic in December 2020.[3]
