The Silver Creek Cliff Tunnel and adjacent Gitchi-Gami State Trail, Duluth, Minn.

Re the feature ?EUR??,,????'?????<

An excellent job of highlighting a wonderful project for Mn/DOT and the state. The photos that you included really help to tell the story of the uniqueness of the site, the quality and complexity of the design and the way in which the public is using and enjoying the trail. Great job.

Stephen, you forgot to add some important facts about our neighborhood, Carlisle. Carbine Development did not make any provisions to take care of the underground wet weather springs, so houses have water under them like mine, we have sink holes in the sidewalk around the green.

Knowing where utility lines are buried is important, of course. Pipes or lines installed decades ago may now be at different depths due to subsequent building and construction. CGA estimates there were approximately 680,000 underground line strikes in 2004, resulting in injuries, damages and service outages.

To add additional value to this service, mark outs should be performed at the beginning of site development projects. This way the mark outs could be located during the initial survey phase and the information used for design purposes. It is a little too late to find subsurface utilities after the design, approval and permitting process are complete and the contractor is ready to dig.

The precision cuts of this 18-ft. dia. porcelain mural is via waterjet technology and computer guidance. The orifice diameter of the jet nozzle is .25 mm to .35 mm. The typical assembly consists of a sapphire (ruby or diamond) orifice and a precision stainless steel mount with an abrasive feed chamber, from which garnet or a sand-like substance enters the water stream.

Excellent story and application of this technology. Ruby technology, when applied into high-pressure fog nozzles utilized in special-effects and humidification fog systems, provides a 20-year life to the nozzle orifice vs. 1,000 hours on ordinary steel nozzles. We patented and successfully applied this ?EUR??,,????'?????<
