“Now fully paved and stretching from the Island County Fairgrounds to Brooks Hill Road, a pedestrian walkway in Langley is open to foot and wheeled traffic. But how well those mixed uses get along on the 6-foot-wide path has yet to be seen.Neither a sidewalk nor a bicycle path, the walkway is a hybrid transportation lane designed to accommodate walkers, runners, and cyclists. A road paving crew put the final layer of asphalt atop the walkway last week, and since then a striping crew and Langley city employees have been separating the walkway from traffic with solid white paint lines, large reflectors, and signs reading Pedestrian Only.On Camano Avenue and much of Park Street, the walkway is completely separated from the roadway by a grass median. In other areas the walkway is little more than a wide, paved should along the road.So far, the walkway is attracting pedestrians. Babe Parnell said she takes daily walks on the new cross-town path. Along the way, she said she sees plenty of people of the same idea.I see a lot of people using it, she said.Langley Police Chief Bob Herzberg said last week that the walkway is a safe place for children on bicycles and walkers to travel when they need to get across town. But, he said, drivers should not expect all non-motorized travelers to use the walkway.Bicyclists are welcome to use it as a bike lane, but they’re not required to, he said.The size of the walkway is an issue for future bicycle traffic. Jack Lynch, the city’s planning official, said the walkway is too narrow to meet federal standards for a bicycle lane. It also lacks a speed limit, like the 10 m.p.h. limit posted on Seattle’s Burke-Gilman Trail. For the time being, Lynch said cyclists can use the lane as long as they ride safely when near pedestrians. He said the Pedestrian Only postings along the walkway should remind cyclists of that responsibility.It is first and foremost a pedestrian way, he said.If having both walkers and riders on the walkway proves to be a problem in the future, cyclists could be prohibited from using it, Lynch said.The section of walkway along Sixth Street, Park Street, and Third Street cost $250,013 and was built over three years. The federal government provided all the funds for the project. Other walkway projects competed by the city during the past decade are paths along Camano Avenue, along Warf Street, and on Cascade Avenue. Lynch said the city will begin construction on a walkway and drainage project along Anthes Avenue next year. “
