The first stretch of long-awaited changes in the road system between Rosslyn and Clarendon in Arlington opened last week with the debut of Clarendon Blvd., an eastbound route that will parallel westbound Wilson Blvd. between Rosslyn and Clarendon.

The premiere was met with mixed reaction from some county business owners.

Paul Robinson, who has operated his Curry Copy Center shop at 1515 N. 17th St. in Rosslyn for eight years, discovered he was now at 1515 Clarendon Blvd.

For some reason, Robinson said, county officials failed to notify him of the change in advance.

Although he said he understands the need for the changes in the road system, he objects to having a Clarendon Blvd. address when he's trying to promote his business as being in Rosslyn.

"Most people think of Rosslyn and Clarendon as two separate geographical areas," he told the County Board last week.

Although all the planned road changes will not occur for another one to two years, the stretch of Clarendon Blvd. replaces portions of Fairfax Drive and N. 15th, N. 16th and N. 17th streets.

Those segments, which consist of new and existing streets, are: Fairfax Drive between Washington Blvd. and N. Daniels Street; the newly constructed section that replaces N. 15th Street between N. Danville and N. Veitch streets; N. 16th Street between N. Uhle and N. Scott streets, and N. 17th Street between N. Scott and N. Nash streets.

William C. Scruggs, the county's traffic engineering chief, said all existing street numbers will remain the same, but the street name will be changed to Clarendon Blvd. The change affects eight houses, 63 apartments and 121 businesses.
