GLENWOOD SPRINGS – Motorists, cyclists and pedestrians will have to skirt around another city construction project starting today. This newest project will bring sewer and water line improvements to the intersection that connects 23rd Street, South Grand Avenue and Glen Avenue, and reconfigure the intersection. City engineer Larry Thompson said the project will improve existing sewer lines, replace old water lines and make the intersection safer for drivers, bicyclists and pedestrians. In all, Thompson expects the $393,000 project to last about six weeks.Workers from Dow Construction will be mobilizing equipment and supplies today. Once the work starts in earnest, the angled exit onto South Grand Avenue will be permanently closed.Turns onto South Grand will be blocked during the construction project.Access to businesses and residences can be gained using 27th Street. Also, 23rd Street on the east side of Grand Avenue will be closed between Alpine Bank and Big Sid’s Liquors for the first few weeks of the project. Motorists are encouraged to use 20th or 24th streets. Once finished, the intersection will be squared-off like most intersections with crosswalks across each of the four streets. Those crosswalks will be made of colored stamped concrete, giving a preview of the crosswalks that are planned to be put in at downtown streets in 2004 during the Grand Avenue Paving Project. Two lanes of traffic on Grand Avenue will be maintained for most of the 23rd Street project, but lanes could be shifted over, similar to the arrangement along the water line project currently being done downtown.Contact Greg Mass: 945-8515, ext. 511gmasse@postindependent.com
