Last week, workers began construction on the intersection of Glebe Road and N. Fairfax Drive. The improvements are part of a pedestrian safety improvement project along Glebe Road that will spread to the Wilson Blvd and Carlin Springs Road intersections later this year.
The upgrades include installing new traffic signals, pedestrian crossing signals, street lights and trees. The intersections will also be reconfigured to improve safety. For example, the pedestrian “pork chop island” will be removed in front of Marymount University’s “Blue Goose” building, according to Tom Hutchings, Capital Project Manager with Arlington’s Department of Enviromental Services Division of Transportation.
“It tightens up the crossing distances at each intersection,” he said.
The red light camera that monitors northbound Glebe Road traffic at Fairfax Drive will remain in use during construction. Although the timing of the traffic lights will not change immediately, it will be evaluated later and tweaked as necessary.
“The timing is continually analyzed with every project we do,” Hutchings said. “It will be studied upon completion of the new lane geometry to optimize the intersection.”
The new traffic lights that were strung over the intersection last week are temporary; the permanent lights will be mounted on upgraded poles with mast arms. The previous poles were based on standards from the 1970s and did not meet the electronic wiring and mast arm standards in the current codes.
The improvements at the three intersections are part of a $2.5 million VDOT project that is locally administered by Arlington County. About 80 percent of the funding comes from federal and state sources, and about 20 percent comes from the county.
Although a number of pedestrian-vehicle accidents have occurred along this stretch of Glebe Road in recent years, such as the deadly cab accident last July, the intersections have been the subject of extensive studies since 2000.
“It is precipitated from acknowledgement of the high level of pedestrian activity in the area,” Hutchings said. “It’s to improve pedestrian and bicyclist safety along Glebe Road where a lot of development has occurred over the past 10 years, and pedestrian use of Glebe Road has increased.”
Work on the Fairfax Drive intersection is expected to be finished by mid-June. The Wilson Blvd. intersection should be completed in August, and Carlin Springs in October.
