Ashland’s Interstate 5 bridges combine architecture with state-of-the-art bicycle technology

« Back to the April 2010 edition

Long-planned improvements at both of Ashland’s Interstate 5 exits — exit 14, Green Springs Highway (Oregon 66) and exit 19, North Ashland interchange — are scheduled to begin in earnest this summer as contractors initiate two separate projects for ODOT.

Brush clearing and other initial site work commences in spring, with heavy construction expected to begin in June and July. The project is expected to be completed by mid-2012.

The Green Springs Highway Bridge at I-5 exit 14 is being widened from the center out to accommodate higher traffic volumes and improved bicycle and pedestrian safety. The bridge deck will nearly triple in width and will feature two 12-foot travel lanes, a center turn lane, traffic signals at both ends of the bridge, and bike lanes and sidewalks. Plans call for repairing the existing deck, replacing non-standard bridge rails, and adding roadway lighting, decorative pedestrian lighting and a bike signal.

The South Valley View Road Bridge at I-5 exit 19 will be entirely replaced with a new, wider structure. The replacement bridge will provide two 12-foot travel lanes, a center turn lane, and widened shoulders.

Funding for both of these projects is provided by the Oregon Transportation Investment Act (OTIA).

Art Deco treatments chosen for new bridges

The new bridges at I-5 exits 14 and 19 will feature artistic treatments that reflect downtown Ashland’s historic architecture and natural environment. A nine-member Aesthetic Advisory Committee, appointed by the City of Ashland to make design recommendations for the project, met six times in 2009. After considering several design options, the group recommended an Art Deco theme for the bridges.

The group found inspiration in design details from the rooftop of the 1925 Ashland Springs Hotel. Ten-foot tall concrete pylons at the ends of the bridges are topped by pointed “chevron” designs also found on the hotel’s parapets. The shape also is featured on the supports for the light poles. The pedestrian fencing with a rust-colored powder coating features a central arch design that can be seen on the hotel’s rooftop facade.

In another nod to downtown Ashland, the light poles on the bridge will provide supports for banners. The light fixtures will be “dark-sky compliant” to minimize any light pollution at night.

The exit 19 design will be a more simplified version of exit 14. Both interchanges will be painted a light tan color to match their natural surroundings. New landscaping will also be included.

Bridge designs for I-5 exits 14 and 19 were shared with the public on April 8. The open house, held at the Best Western Windsor Inn in Ashland, provided the public with the opportunity to meet project staff and review the final design plans.
