Timberline Road Improvements
PROSPECT road TO BLACKBIRD drive
The proposed improvements are derived from the 2005 Building on Basics (BOB) sales and use tax for capital improvement projects. Interim intersection improvements were constructed in 2005, the upcoming project will take the intersection to it's ultimate improvement level.
In 2011, the Engineering Department completed an Arterial Intersection Prioritization Study which listed the Prospect Road and Timberline Road intersection as one of the top ranked locations for needed safety and operational improvements. Existing problems which brought this intersection to the top of the list included: significant congestion during the peak hours, higher than average vehicle accident rates, and intersection delay. The project will include multi-modal facility improvements to create a safer and more efficient intersection for all users.
- Improve safety and overall efficiency for vehicles, bicycles and pedestrians
- Reduce the accident rate by modifying the configuration of the intersection
- Improve air quality by reducing vehicle wait time (delay)
Proposed Improvements (Conceptual Design)
The Intersection Study identified the need for a "free" right turn lane from eastbound Prospect Road to southbound Timberline Road; along with an acceleration lane on Timberline Road to receive this turning movement. Along with this intersection evaluation, the City will investigate the current and future traffic projections at the Prospect Road and Riverside Avenue intersection. The Riverside to Prospect to Timberline connection (in both directions) is one of the dominant traffic movements in the area.
As part of the conceptual design phase, the City will examine the ultimate right-of-way acquisition area for southbound Timberline Road between Prospect Road and Blackbird Drive. This will allow us to install the ultimate sidewalk and bike lane configuration for Timberline Road. Existing medians will be re-purposed, along with the construction of new medians, to meet the recently revised Streetscape Design Standards and Guidelines.
The project will be funded through the Building on Basics (BOB) Intersection Funds from the voter approved quarter-cent sales tax. The project is identified as "Timberline Road - Drake Road to Prospect Road" from the 2005 ballot language. More specifically, the ballot language stated, "This project will expand Timberline Road to four (4) lane arterial standards including travel lanes, sidewalks, bike lanes, landscaped medians, and other necessary improvements. The project will include improvement to the Timberline / Prospect intersection and all its approaches to add additional turn lanes".
- Preliminary Design January-June 2013
- Final Design July-December 2013
- Right-of-Way Acquisition Phase July-December 2013
- Construction Summer 2014 (Right-of-Way Dependent)
A detailed communication plan is being developed and will be implemented with the preliminary design phase through construction. The communication plan will highlight milestone dates, press releases, social media outlets and specific outreach methods for residents and the travelling public.Check back here often for exact construction dates. Additionally, the project construction information will be available on our interactive trip planner, FC Trip.
