Editing Interstate 129 (section)

==Route description==
I-129 begins along [[U.S. Route 20 in Nebraska|US&nbsp;20]] on the western edge of [[South Sioux City, Nebraska]], just west of exit&nbsp;1, a [[cloverleaf interchange]] with [[U.S. Route 75 in Nebraska|US&nbsp;75]] and [[U.S. Route 77 in Nebraska|US&nbsp;77]]. US&nbsp;77 travels north through South Sioux City before ending at [[Interstate 29 in Iowa|I-29]] in [[Sioux City, Iowa|Sioux City]] while US&nbsp;75 joins I-129 and US&nbsp;20. {{convert|1|mi|km|spell=In}} later, I-129/US&nbsp;20/US&nbsp;75 intersect Dakota Avenue at a [[partial cloverleaf interchange]]. [[U.S. Route 20 Business (South Sioux City, Nebraska)|U.S. Highway&nbsp;20 Business]] (US&nbsp;20 Bus.) is designated along Dakota Avenue.<ref name=NDOR/>

East of Dakota Avenue, I-129/US&nbsp;20/US&nbsp;75 travels south of South Sioux City and passes through rolling farmland. For the rest of I-129's length, the two directions of I-129/US&nbsp;20/US&nbsp;75 traffic are separated by a [[Jersey barrier]] instead of a grassy median. The three routes cross the [[Missouri River]] and immediately intersect [[Interstate 29 in Iowa|I-29]] at an interchange. Due to the minimum amount of space along the [[Missouri River]] banks, the I-29 interchange is a modified two-level [[Interchange (road)#Combination interchange|cloverstack interchange]]. At I-29, US&nbsp;20 and US&nbsp;75 continue east around [[Sioux City, Iowa|Sioux City]] and I-129 ends.<ref>{{Google maps | url = https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&sll=42.448415,-96.393088&sspn=0.00528,0.009634&g=Sioux+City&ie=UTF8&hq=&hnear=Sioux+City,+Woodbury,+Iowa&t=h&layer=x&ll=42.445834,-96.373959&spn=0.010561,0.019269&z=16 | access-date = February 27, 2010}}</ref>
