<br />D. Left and Right Turn Lanes <br />Generally left and right turn lanes and tapers shall be con.sidered when: <br />. In accordance with G.S. 136- 18(29), the average daily traffic meets or exceeds 4,000 vehicles per <br />day on any secondary route (the average daily traffic should include both the existing traffic plus <br />traffic generated by the proposed development); <br />. Any US or NC numbered route is being accessed; <br />. The District Engineer determines that such treatment is necessary to avoid congestion or unsafe <br />conditions on the state-maintained roadway; or <br />. A TJA identifies a need for an auxiliary lane or taper. <br /> <br />Left and right turn lanes shall be constructed in accordance with the "North Carolina Standards and <br />Specifications for Roads and Structln'es." On an undivided highway or a divided highway with a median <br />width that is inadequate for a left-turn lane, it may be necessary to widen the highway in order to provide <br />for the required turn lanes. For greater detail, see the turn lane nomograph figure in the Exhibits section of <br />the "Policy on Streeland Driveway Access to North Carolina Highways." Should widening be required to <br />acconunodate turn lanes or tapers, the applicant shall be required to acquire the necessary ROW as stated in <br />Section B, Right-of-Way Acquisition. <br /> <br />E. Channelization <br />The applicant may be required to protect the integrity of the highway network by providing channelization <br />to physically prevent improper or illegal turns into and out of a driveway or street. Channelization may <br />include medians and raised traffic islands with curbs. <br /> <br />F. Authority <br />The District Engineer has final authority on decisions regarding iIlfrastructln'e irnprovemen~ and shall <br />inform Cabarrus County of any such decisions regarding infrastructure improvements.
