TRIANGLE TRANSIT AUTHORITY Memorandum Date: December 11, 1992 To: Board of Trustees Triangle Transit Authority From: Planning Committee Subject: Report from the Planning Committee Concerning the Durham Freeway (East- West Expressway) Extension Bridge Across the N.C. Railroad On December 10, 1992, the Planning Committee received a report from Bob Grabarek and Neat Salmon of the North Carolina Department of Transportation concerning the highway bridges planned for the extension of the Durham East-West Expressway across the North Carolina Railroad. • The road project will complete the Durham East-West Expressway from its current terminus at 15-501 to I-85. The freeway will cross over the North Carolina Railroad just east of the intersection with I-85. The NCDOT staff has designed the bridge over the railroad for one set of tracks only. The NCDOT reported that any change from the current bridge design will delay the project by at least one year. With the attorney for the North Carolina Railroad, the General Manager encouraged NCDOT staff to consider constructing the bridge for four sets of tracks. Such a configuration would allow two tracks for heavy rail and two tracks for light rail. The NCDOT Public Transportation and Rail Division staff has recommended that two tracks would adequate, but the project is currently proceeding without any change in the design. NCDOT staff estimates that an extension in the bridge for two tracks will cost an additional $157,100, and an extension in the bridge for four tracks will cost an additional $659,600. The Planning Committee discussed the issue and requested that the Board as a whole hear the. report before making a recommendation concerning bridge design to the NCDOT.
