Extra-wide sidewalks and sound walls also are being built throughout the project. The image is one of motorists driving along El Cajon Boulevard, passing business after business, and with the exception of seeing the on and off ramps, never knowing they crossed a freeway. The residents in the area can look forward to much quieter neighborhoods when the project is completed. Aesthetics have played a major role in the construction of sound walls, bridges, sidewalks, fences, light posts, bridges and parks. Cobblestone features are used around the project, as are decorative railings and street lamps.
Architectural consistency is important.
Three community parks, including one on top of the freeway, will be built or improved, and four landscape projects will begin along the freeway even before the final pieces of the construction project are completed. How about the placement of 12 miles pipe for water, sewer and storm drain facilities all within the 2.2-mile construction area. The need is, and has been, intense. Compare that number with the 210,000 motorists per day who use the congested Interstate 805 just a few miles away, many of whom will switch to this new section of I-15 when it is completed. One of the biggest challenges on this project in particular is building a new freeway while accommodating the existing traffic flow.
