RH Roadways Highway H-365 Realignment For NSWC Crane Division Crane, Indiana April 29, 2004April 2, 2004 Mr. Dave Burrus Naval Surface Warfare Center, Crane Division Engineering Design Branch Bldg. 2516 Crane, IN 47522-5082 Dear Mr. Burrus: Since we first met, RH Roadways has been working intensely to develop a solution to your traffic navigation problem. Roads H-365 and H-367 are very difficult to maneuver for large tractor-trailers due to varying slopes, multiple railroad crossings, and the curvature of the road. This route is a crucial one in that it connects a major highway (H-101) to a large ordinance storage facility (Building 3333). RH Roadways has been asked by NSWC to design a road that will make travel easier and safer for tractor trailers. In our approach to find a solution, we completed a site assessment, examined the subsurface, and closely followed all codes and regulations. The final decision, as discussed in January, was to design the alternative for realignment to the south of the existing road. The final design includes horizontal and vertical alignments, pavement and hydraulic designs, construction alternatives, erosion and sediment control plans, and a cost analysis. As requested, our recommended design alternative accomplished all of the goals set forth in the beginning of this project. Vertical grade was reduced to a maximum of three percent, possible railroad crossings were limited to four, and cut and fill quantities were minimized. The total cost of the final design is estimated to be $365,000. We would like to take this time to express our appreciation for the project. This was a great opportunity to use what we have learned and apply it in all of the aspects of design. Your time was greatly appreciated and we hope future seniors will have the opportunity to work with NSWC. If you have any questions or comments, feel free to contact us. Sincerely, Tim Brown Drew Furry Project Manager Project Engineer Jim Walter Tabatha Doughty Project Engineer Project Editor CC: Robert Houghtalen Enclosure: Final ReportExecutive Summary The Naval Surface Warfare Center (NSWC), Crane Division, is located in southern Indiana. NSWC Crane Division is a major source for countless electronic and technical services, including ordinance development, testing, and storage. Therefore, efficient ordinance movement is critical to the NSWC mission. However, one specific building does not allow for easy access to the main highway. This key facility, Building 3333, is located only 0.6 miles from the highway. Its existing access roads are narrow, full of sharp curves, and cross several active railways. Given these conditions, the roads (HWY 365 & 367) are very difficult to navigate for commercial semi-trailers. The goal of RH Roadways is to provide NSWC with recommendations to re-align or relocate the roadway for easier navigation of tractor-trailers, while limiting railroad crossings. Five alternatives were assessed in a matrix of client-developed criteria to identify the best solution. The best solution was designed and includes: horizontal and vertical alignment, hydraulic design, construction planning, erosion control measures, plans and specifications, and final cost analysis. RH Roadways recommendation includes construction of a new route that uses a portion of the existing roadway. The eastern half of the road (H-365) will be moved south to allow for a straighter road with reduced vertical grades. All design goals were met using this alternative including: a reduction in railroad crossings from seven to four, a reduction of grade from twelve to three percent, and a decrease in degree of curvature from 100 feet to 500 feet. The total cost of construction was estimated to be $375,000. Construction will be done in two stages utilizing flexible pavement. The first stage will be the realigning of the eastern half located to the south of H-365, and the second stage will involve tying into the existing concrete slab near Building 3333. Erosion will be minimized during construction, and natural grass cover will be the main control.Table of Contents 1.
