The bypass bisected a section of <a href="/wiki/McNee_Ranch_State_Park" title="McNee Ranch State Park">McNee Ranch State Park</a>, and was opposed by community and environmental groups. By 1975, 55% of the <a href="/wiki/Right-of-way_(property_access)" class="mw-redirect" title="Right-of-way (property access)">right-of-way</a> had been acquired, when work on the proposed bypass was abandoned due to public opposition. </p><p>Most environmentalists supported a <a href="/wiki/Tunnel" title="Tunnel">tunnel</a> as a more environmentally sensitive alternative to the <a href="/wiki/Martini_Creek" title="Martini Creek">Martini Creek</a> Bypass. A short tunnel built in 1908 by the <a href="/wiki/Ocean_Shore_Railroad" title="Ocean Shore Railroad">Ocean Shore Railroad</a> went through the area, but was destroyed during <a href="/wiki/Prohibition_in_the_United_States" title="Prohibition in the United States">Prohibition</a>, to keep it from being used by <a href="/wiki/Alcoholic_beverage" title="Alcoholic beverage">alcohol</a> <a href="/wiki/Rum-running" title="Rum-running">smugglers</a>. The <a href="/wiki/Sierra_Club" title="Sierra Club">Sierra Club</a> proposed building a tunnel to bypass the road in 1973. A <a href="/wiki/California_Department_of_Transportation" title="California Department of Transportation">Caltrans</a> study in 1974 determined that a tunnel would be a viable alternative to the current road or a proposed inland <a href="/wiki/Freeway" class="mw-redirect" title="Freeway">freeway</a> bypass. However, the state dropped the idea in the late 1970s. </p><p>A major slide in 1983 brought the problem to the public attention again. In 1985 Caltrans proposed the Martini Creek bypass as the preferred solution. However, the Sierra Club sued to stop construction, as California law requires that State Route 1 be restricted to two lanes in <a href="/wiki/Rural" class="mw-redirect" title="Rural">rural</a> areas. The 101-foot-wide (31 m) road bed, complete with continuous uphill <a href="/wiki/Passing_lane" title="Passing lane">passing lanes</a>, runaway truck ramps, and extra-wide shoulders, would be the widest two-lane road in the state. Again the state decided to return to the status quo. </p><p>A five-month outage caused by a slide in January 1995 again brought public scrutiny to the stretch of highway. In April, Caltrans documents were discovered that showed the agency had intentionally overestimated the costs of a tunnel, to support the freeway bypass. In July, the <a href="/wiki/Federal_Highway_Administration" title="Federal Highway Administration">Federal Highway Administration</a> ordered Caltrans to re-evaluate a tunnel to bypass Devil's Slide. On November 5, 1996, San Mateo County voters approved <a href="/w/index.php?title=San_Mateo_County_Measure_T_(1996)&action=edit&redlink=1" class="new" title="San Mateo County Measure T (1996) (page does not exist)">Measure T</a> by 76%, changing the county's stated preference from construction of the bypass to construction of a tunnel. On November 9, Caltrans changed its position, supporting a bridge and tunnel as the best environmental, economic, and popular alternative to Devil's Slide. </p><p>Ground was broken for the new tunnel on May 6, 2005. Boring of twin 30-foot (9 m) diameter tunnels started September 17, 2007, and was completed in 2011.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Breakthrough on the northern bore occurred on September 30, 2010.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> With the completion of the tunnels in 2013, the old Devil's Slide highway was converted into a <a href="/w/index.php?title=Devil%27s_Slide_Trail&action=edit&redlink=1" class="new" title="Devil's Slide Trail (page does not exist)">trail</a> for hikers and bicyclists.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The tunnels opened to traffic on March 26, 2013.<sup id="cite_ref-Mendoza_4-0" class="reference"><a href="#cite_note-Mendoza-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="References">References</h2></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite id="CITEREFMichael_Cabanatuan2011" class="citation news cs1">Michael Cabanatuan (4 August 2011). <a rel="nofollow" class="external text" href="http://www.sfgate.com/bayarea/article/Devil-s-Slide-tunnel-work-falls-behind-schedule-2336430.php">"Devil's Slide tunnel work falls behind schedule"</a>. <i>The San Francisco Chronicle</i><span class="reference-accessdate">.
