Work progresses on St. Johns. Portions of the project have sidewalks installed along with two new lanes of pavement. The project will be complete by spring 2009.
Project Number: 301422
Project Limits: NE St. Johns Road from NE 50th Ave. to NE 72nd Ave.
Current Phase: Construction started in August 2007
Project Type: Widening existing two-lane road to a five-lane Principal Arterial
Road Condition Update: NE 109th will be closed during the day Monday, May 12 for paving. NE 72 Ave. from NE 110th St. to St. Johns will be closed for paving on Wednesday, May 14. Please follow detour signs. Local access will be available. This schedule is weather dependent.
N.E. St. Johns Road Project Description
This project will widen St Johns Road to a 5-lane Principal Arterial configuration with four travel lanes, raised median with turn pockets, bike lanes and sidewalks. Currently the roadway has two lanes, no median and an approximate one-foot shoulder. The intersection of St. Johns Road and NE 72nd Avenue will be reconfigured and a new signal installed.
The project will also improve a portion of NE 72nd Avenue, from NE 110th Street north through the intersection of St. Johns Road and NE 72nd Avenue. Drainage improvements, wetland mitigation, and other utility modifications (sewer and water) will be included in the project. Some minor realignment work will be done at NE 109th Street to correct a severe crossing angle.
The speed limit has been reduced to 25 mph throughout the project area, and speed bumps added to protect drivers and construction workers. Total project cost, including all utility work, will be about $13.6 million. Construction will be complete by spring 2009.
Why is Clark County doing this project?
The current roadway is inadequate to serve the needs of this growing area of the county. This project will reduce traffic congestion while meeting the safety needs of the traveling public including bicyclists and pedestrians. A companion project along N.E. 72nd Avenue will further improve travel in this area. The St. Johns project contractor has already cleared along the east side of the 72nd Avenue project area to facilitate utilities relocation. Construction work on N.E. 72 Avenue road improvements began the week of November 19.
When complete, this wetland mitigation project will provide important environmental and stormwater management improvements.
Environmental Information
Both the St. Johns and NE 72nd Ave. roadway improvement projects affect wetlands. Local, state and federal environmental regulations require mitigation for these impacts.
Building wetland mitigation includes digging out existing soil to drop the ground elevation and allow water to pond slightly and create a higher quality wetland. Woody debris has been added. Several thousand native plants will be installed next year, then maintained and monitored for a period of ten years. The grading and planting plan was thoroughly reviewed by permitting agencies over the course of several years.
