NH-129-1(30); C.N. 32275I-129, SOUTH SIOUX CITY
PROJECT INFORMATION SHEETAs of October 2019
LOCATIONThe proposed project would resurface approximately 3.23 miles of Interstate 129 (I-129) in South Sioux City in Dakota County. The project would start approximately 0.55 miles west of the grade separation of I-129 under southbound U.S. Highway 75 (US-75)/U.S. Highway 77 (US-77) at mile marker US-20 (MM) 428.37 and extend east to the bridge over the Missouri River at MM 3.05. Construction may begin and/or end approximately 500 feet ahead of or beyond the actual project limits to accommodate transitioning the pavement.
PURPOSE AND NEEDThe purpose of the proposed project is to preserve the I-129 transportation asset, improve the reliability of the transportation system, and perpetuate the mobility of the traveling public. The need for the project is based on the condition of the existing pavement and bridge structures.
SCOPE OF WORKProposed improvements on this project would include milling and resurfacing with asphalt the existing I-129 roadway and shoulders and the US-75/US-77 & Dakota Ave Interchange ramps and shoulders. Bridge structures S129 00008, S129 00107, S129 00123 and S129 00150 on I-129 would undergo repairs. Bridge structures over I-129 at US-75/US-77, S129 00038 & S129 0039 and at C Ave, S129 00201 would also undergo repairs. Additional work would include guardrail improvements and replacing sign trusses over the roadways.

CONSTRUCTION SCHEDULEConstruction could begin as early as spring 2020 and be completed in approximately 2 years.
ESTIMATED COSTThe estimated cost of the proposed project is approximately $11.6 million. Funding for the project would derive from state and federal funding sources.
ACCOMMODATION OF TRAFFICThe proposed resurfacing and bridge repair work on I-129 and US-75/US-77 would be constructed under traffic with lane closures controlled with approved temporary traffic control; however, local traffic utilizing the ramp accesses along I-129 within the project area would require detours. Designated detours for these ramp accesses would be provided; one would utilize US-75/US-77, N-35, and N-110/G Avenue, the other would utilize US-77, W 28th Street, and Dakota Avenue. The bridge repairs and ramp closures at this location would be separated into three groups, and work on each bridge group would not occur at the same time as another bridge group. These detours could be in place for up to two years. The proposed project would also require detouring C Avenue for repair work on the bridge over I-129. A designated detour would be provided utilizing E 39th Street, Dakota Avenue/IBP Avenue, and E 48th Street. See the maps on the inside of the handout for more details.
Additionally, the project would require short duration night-time detours of I-129 and US-75/US-77 traffic during removal and installation of overhead signs and structures. The detours would be required for eastbound and westbound I-129 and northbound and southbound US-75/US-77. Only one direction of traffic would be detoured per night. Eastbound I-129 and northbound US-75/US-77 would have a designated detour utilizing I-129, N-110, N-35, and US-75/US-77. Southbound US-77 traffic would have a designated detour utilizing W 29th St, Old Hwy 20 and I-129. Westbound I-129 traffic from Iowa would have a designated detour utilizing I-29 and US-77. Westbound I-129 traffic originating in Nebraska would have a designated detour utilizing Dakota Avenue, W 29th St and US-77.
RIGHT-OF-WAYThe proposed project would not require the acquisition of additional property rights. Access to adjacentproperties would be maintained during construction but may be limited at times based on traffic phasingrequirements.
POTENTIAL IMPACTSNo wetland impacts are anticipated. Crystal Cove Park and the Dakota City Trail are located near or within the project area. No impacts to these facilities are anticipated.
