The City of Lincoln plans roadway improvements to accommodate growth in the area of North 14th and Superior streets. Phase I of the project will begin this fall and will include constructing 14th Street from Superior Street to I-80. NDOR has already started construction on the I-80 bridge and expects the bridge construction to be completed by early August 2012. The city's project will widen 14th Street to four lanes north of Superior and will include the construction of a multi-lane roundabout at Superior Street.
The detour map can be found here on page 3.
UPDATE: An educational meeting on roundabouts will be held on July 17, 2012, from 5 - 7 p.m. at Campbell Elementary, 2200 Dodge Street (just east of the 14/Superior intersection).
