Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

138 ALASKA Overhead snow poles (delineators cantilevered to the edge line suspended from a steel pipe that is mounted 12 ft from the edge line) are available. CALIFORNIA A STOP pavement message is placed such that the tops of the letters are 8 ft from the stop line in advance of all stop lines at signalized or STOP sign controlled intersections. Wrong-way arrows (one in each direction) are used at locations near intersections and at a maximum of one-mile spacing where motorists could perceive that they are on a one-way roadway when, in fact, they are on a two-lane, two- way highway. Following are some typical situations: • Construction sites where a two-lane highway is being converted to a freeway or an expressway. • Two-lane, two-way highways where ultimate freeway or expressway right-of-way has been purchased and grading for the full width has been completed. • Two-lane, two-way highways following long sections of multi-lane freeway or expressway. The SLOW SCHOOL XING pavement message shall be used in advance of all yellow school crosswalks that are not controlled by STOP signs, YIELD signs, or traffic signals. The words shall be yellow with the final word in the sequence, XING, at least 100 ft in advance of the crosswalk. The SCHOOL XING pavement message shall be used in advance of all white school crosswalks. The SCHOOL pavement message shall be restricted to a single lane. COLORADO Solid 8-in.-wide lane lines separating mandatory left-turn lanes from adjacent through lanes are extended beyond the stop line and may be curved slightly to the left just before they terminate. Lane lines separating mandatory right-turn lanes from adjacent through lanes are extended beyond the stop line to the extension of the edge line of the cross street and are curved slightly to the right just before they terminate. GEORGIA A different spacing pattern is specified for lane-use arrows and ONLY messages on intersection approaches at the end of exit ramps. U-turn arrows and combination U-turn/left-turn arrows are available for use. MONTANA Pavement marking design standards for historical marker turn- outs, mailbox turnouts, and chain-up areas are included in the Montana Traffic Engineering Manual. NEW YORK A diverge arrow is included in the pavement marking symbols that are shown on Sheet M685-5R1 (5 of 5) of New York’s standard design sheets. When a climbing lane is provided on a one-way road- way, a double broken line (10-ft segments with 30-ft gaps) starts at the beginning of the full-width lane and ends 600 ft from the end of the full-width lane. A partial barrier line (a 4-in.-wide solid line on the left-hand side and a 4-in.-wide broken line with 10-ft segments and 30-ft gaps on the right- hand side) starts at the end of the double broken line and ends 100 ft from the end of the full-width lane. Lane-reduction arrows are not shown. VIRGINIA Standards for the transition from a left-turn lane in one direction to a left-turn lane in the other direction in a paved center median area are shown in Virginia’s design standards. DISTRICT OF COLUMBIA On Pennsylvania Avenue between 3rd Street and 15th Street all pavement markings are white, including the centerline, because this is a special historic street and does not follow the MUTCD. LOS ANGELES, CA Pavement markings associated with pedestrians and schools, such as crosswalks and school pavement messages, may be yellow. NEW YORK, NY A gridlock box is shown inside of high-visibility cross- walks on Drawing TCW-1 of New York City’s standard drawings. APPENDIX R Non-MUTCD Items
