SOUTH SIOUX CITY – For those interested in knowing more of the details about proposed improvements to Interstate 129 (I-129) in northeast Nebraska are invited to attend a public information open house.
According to a release from the Nebraska Department of Transportation, the open house will be held at the First Lutheran Church (3601 Dakota Ave.) in South Sioux City on Thursday, October 10 from 5 – 7 p.m.
The proposed project is 3.23 miles in length along I-129 located in South Sioux City. 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 approximately U.S. Highway 20 (US-20) mile marker (MM) 428.37 and extend east to the bridge over the Missouri River at I-129 MM 3.05.
Proposed improvements on this project consist of bridge repairs, bridge overlay along with removing and replacing guardrail. The roadway, surfaced shoulders as well as ramps and loops at both the US-77 and Dakota Avenue interchanges would be milled and resurfaced with asphalt. Several bridge structures on I-129 would undergo repairs and several bridge structures over I-129 at US-75/US-77 would also undergo repairs. Additional work would include guardrail improvements and replacing sign trusses over the roadways.
The 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. These detours could be in place for up to two years as additional detour information will be provided at the meeting.
The project is tentatively scheduled to begin in the spring of 2020 and could be completed by the fall of 2021.
Personnel from NDOT will be present to answer questions and receive comments. Information regarding the proposed project will be made available on the NDOT website at www.dot.nebraska.gov/projects/future-projects/ by clicking on the “I-129, South Sioux City” link.
