$17M Sixth St construction project begins this month
By: The Brookings Register

The South Dakota Department of Transportation says the Highway 14 (6th Street) project in Brookings is scheduled to begin March 20 with Phases 0 and 1.

A public meeting has been scheduled for March 20 at 5 p.m. in the Brookings City Hall Council Chambers located on the 3rd Floor of the City and County Government Center, 520 3rd St., to provide a project overview and schedule of work progression.

The planned improvements include new surfacing, curb and gutter, storm sewer, sidewalk, traffic signals, a new five-lane bridge with sidewalk, numerous intersection improvements, roadway lighting and city utility work. More information on the phases and detailed work can be found on the project website: http://www.sddot.com/travelers/projects/6thStBrkgs/default.aspx.

The 4 phases of construction which have been established for this project are as follows:

  • Phase 0:  Preliminary prep work for project which includes installation of temporary traffic signals throughout the project and detour routes, traffic barrier installation, temporary surfacing at entrances/intersections for carrying traffic and asphalt strengthening/overlay on Minnesota Drive for local detour traffic.
  • Phase 1:  Install traffic control on 6th Street moving westbound traffic to eastbound lanes to allow for construction of the westbound lanes; install traffic control on I-29 switching northbound traffic to southbound lanes and vice versa for structure removal and construction of Phase 1 bridge; removal and reconstruction of northbound on-ramp and southbound off-ramp at I-29 Exit 132 (limited to 21 days); and closure of the 22nd Avenue intersection from May 8-Aug. 11 (limited to 75 days), to allow for intersection reconstruction and utility installations.
  • Phase 2:  Install traffic control on 6th Street moving traffic to newly constructed westbound lanes and Phase 1 bridge to allow for the construction of eastbound lanes, removal of existing eastbound bridge and complete Phase 2 bridge; removal and reconstruction of southbound on-ramp and northbound off-ramp at I-29 Exit 132 (limited to 21 days).
  • Phase 3:  Complete proposed median pavement, curb and gutter, sidewalks and service roads that were not completed during Phase 1 and 2.

Through traffic and over-width traffic will be detoured to I-29 and the U.S. 14 bypass. Local traffic will be detoured onto State Avenue and Sunrise Ridge Road from the south and 9th Street and Sunrise Ridge Road from the north during the 22nd Avenue intersection work. No parking will be allowed along the detour routes for the duration of the closures and will be signed accordingly.

Two-way traffic will be maintained on the remainder of 6th Street during construction with one half of the roadway constructed at a time. Drivers needing to access the industrial park area are encouraged to use the U.S. 14 bypass and 34th Avenue.  Please allow extra time for travel if utilizing these routes.

There will be a number of speed reductions including, 45 mph on the Highway 14 bypass along the detour route; a 30 mph speed reduction for 6th Street through the project limits and I-29 traffic speed will be reduced to 65 mph through the bridge construction limits just north and south of Exit 132.

The contractor will be installing “Business Signs” along the local detour routes to help direct the local traffic to access points for the affected businesses.

Interim completion for the project is Nov. 3, 2017, which includes Phase 0-2.  Overall field completion date is June 30, 2018, which includes Phase 3.

The public is invited to attend weekly meetings to discuss progress and sequencing.

Meetings will be held every Thursday at 9 a.m. at the Department of Transportation building located at 2131 34th Ave., Brookings.
