Drawer DFW Dallas/Fort Worth Airport, TX 75261 Re: Royal Lane Extension IH 635 - Bethel School Road Dear Mr. Churchwell: As you requested, we have obtained copies of construction plans for Royal Lane from south of IH 635 (LBJ Freeway) to Freeport Parkway and are transmitting one set with this letter. Those plans include the typical cross- section included with each roadway design. The attached plans for Royal Lane are for the east side only. The west half of the Royal Lane paving, according to our conversation with Mr. Aaen, was built by DFW. DFW should have copies of those plans. Although the cross-sections indicate no lime stabili- zation, it is our understanding that the roadway was constructed in accordance with City of Irving standards which require six-inch lime stabilized subgrade. We were informed by the engineer that the soils investigation report for these projects has been misplaced. Please do not hesitate to contact us if additional information is needed fo~ your review.
