What is with all the non breaking spaces? This would be much more efficient as a styled list. Not what you wanted to know but eh..
<ul class="sidenav">
<li><a href="approach.
html" class="sidenav">OUR APPROACH</a></li>
<li><a href="safety.
html" class="sidenav">Safety</a></li>
<li><a href="projectcontrols.
html" class="sidenav">Project Controls</a></li>
<li><a href="industryaffiliations.
html" class="sidenav">Industry Affiliations</a></li>
</ul>
Then style it with
CSS accordingly.
