Opinion - Freeway canyon: Put a lid on it

An ugly "wound" that has festered for a half-century in downtown Vancouver can be healed, and the community ought to jump at the opportunity. It is the Interstate 5 canyon, created by construction of the interstate freeway in the 1950s.
The route splits Vancouver east and west, symbolically separating downtown from Clark College, Hudson's Bay High School, the Fort Vancouver Regional Library, the Clark Public Utilities building and the Vancouver National Historic Reserve.
Now, a chance to correct the ugly gash through the downtown area arises with construction of a new I-5 Columbia River bridge, and reconfiguration of the freeway and exit and access ramps. Construction could start in 2009.
It would be well to cap the freeway along several sections of the city all the way from the river to the 39th Street interchange, but that does not appear feasible.
Within reach, if sufficient public pressure is applied, would be capping the freeway from Seventh Street to Evergreen Boulevard.
Seattle where a Freeway Park and convention center have been built over the I-5 freeway offers a prime model for turning a downtown concrete channel into something of functional beauty.
Franklin Green, assistant engineering design manager for the Columbia River Crossing project, said the city has asked the Crossing staff to look at capping part of the freeway. Green said the staff will take a "technical look" at capping.
Enthusiastic support for a downtown freeway lid surfaced last week from George (Bing) Sheldon, chairman of SERA Architects of Portland, once described as the "patriarch of Portland design and planning."
Sheldon, a board member of the Vancouver National Historic Reserve Trust, was attending a presentation of bridge construction options to the board. Doug Ficco, director of the Columbia Crossing project, and Lynn Rust, engineering design manager, also participated. The Trust is concerned that one of 12 bridge construction alternatives would chop off a portion of the historic 1909 hospital on the east side of the freeway.
Option 9 calls for the widened freeway to take land from one side or the other, and sometimes both sides. Sheldon suggested a cover. The hospital site is opposite Killian property on the west side that could be affected.
Linking east to west
Interviewed after the Trust meeting, Sheldon said the lid could offer easy access to a restaurant or shops as the Reserve grows from 1 million visitors a year to 2 or 3 million.
A pedestrian walkway over the freeway to the Reserve at Seventh Street has been planned for years. The extended lid would mean much more linkage east and west in a community sense.
Public input is especially important now because the 12 alternatives, which include bridge construction and the network of interchanges access and exit ramps will be narrowed to two to four final alternatives by the end of the year. Those will be scrutinized and a draft environmental impact statement issued early 2008, according to the Columbia Crossing schedule.

Capping a portion of I-5 would be a small part of the complex Columbia River bridge project, which has an estimated price tag of $1 billion to $2 billion. Forty-six years ago, the cost of building a twin Interstate 5 span, and adding a matching "hump" to the 1917 bridge, was financed by $14.5 million in bonds, according to Columbian archives. The elevated hump allows barges and other types of vessels to pass under the spans without interrupting traffic.
Tolls, imposed Jan. 10, 1960, paid for the bonds. The cost per passenger car was 20 cents, but commuter tokens cut it to 15 cents. For those worried history might repeat itself, tolls ended Nov. 1, 1966, four years earlier than forecast.
Opened Feb. 14, 1917, the original I-5 span cost $941,000. The new bridge is supposed to last 100 years. That's close to permanent. The downtown "canyon" has existed for 50 years. Let's not wait another 100 to put a lid on it.
