ST9401-CS 960812August 12, 1996 City of Coppell 255 Parkway Blvd. Coppell, Texas 75019 Attn: Mr. Mike Martin Re; Bridge over Denton Creek Denton Tap Road GTE Telephone Operations Central Area Dear Mr. Martin: GTE is in the process of reattaching two of its ducts onto the bridge mentioned above, since the water line is in place. Since we have several more feet exposed than we did before, we are proposing the following: 1. To replace the transition ends of the existing PVC with split steel duct. Specifications on this duct are following. For each of the two ducts, it will take two 45 degree bends to transition horizontally, a length of straight steel duct, and two more 45 degree bends to transition vertically. 2. To support the pipe with a mechanical clamp supported from the water line's I-beam, using either a side clamp or one which would go underneath the I-beam, as shown on the following. Either clamp would attach to the I-beam without any holes being drilled in the beam. 3. To transition around the abutment extension to a point where we can tie back onto the existing PVCs, rather than dig underneath the abutment extention. If this meets with your approval, please let me know. If I can provide any additional information, please contact me at (214) 318-3832. Sincerely, Mae Beth Whaley 7 Engineer, 0. S.

Then the end of tr~e cable is pulled thro ugh a Solid du,;i and the cable is put back o mo tile reef at the Other aide of e bridge. This t~me conSuming F,fo(;ess can take up to as much as 8 hours with today's Jong fiber.optic cable reels, With Split Steet Duct the duct could be prehUng on the I;riclge then opened up ~ cable i~aced tn tN $pJtt Steel Duct etrm insring the need for figure eightlng bhe oaDle.
