9TH STREET CORRIDOR CONSTRUCTION

Currently, pre-construction activities along the 9th Street corridor are occurring such as potholing, investigation and marking of utilities with chalk paint, mobilization of construction equipment, and set up of traffic control.

Construction of sewer upgrades is expected to begin early to mid-August 2017 and conclude in early spring 2018. Work activities on 9th Street will occur for five blocks from G to L streets and involve:

  • Installation of a 60-inch in diameter combined sewer pipeline using open-cut, tunnel boring and pipe jacking equipment

  • New combined sewer manholes, drain inlets, sewer service connections and other associated work

Construction Phases

To help minimize impacts and maintain traffic movement for local and regional travelers, construction along the 9th Street corridor will involve installation of a new 60-inch diameter combined sewer pipeline using both open cut and tunneling activities.

Construction duration will average about two months per 1 to 1.5 blocks starting in the south and heading north.

While work will generally occur from south to north block by block, five tunneling shafts will be dug at the start of construction. The pits will remain open during construction and protective k-rail in place.

Traffic controls will be in effect directing traffic through the construction zone. To maintain one lane of traffic at all times while allowing for equipment staging and a safe work area, on-street parking will be temporarily taken for the length of the corridor.

Construction Hours

Work will generally take place between 7:00 a.m. and 6:00 p.m., Monday through Friday. Night and/or weekend work may occur as necessary with City approval. All work will be scheduled in observance of the downtown holiday moratorium.

Construction Impacts

During construction, businesses and sidewalks will remain open at all times. Traffic alerts will be sent before any closures and flaggers will be stationed at designated areas to maintain safe travel. A construction liaison will work closely with property owners and occupants throughout construction to inform them of upcoming activities and address concerns regarding potential impacts that may include:
