Benesch worked with the City of Grand Island to evaluate the 13th Street corridor to define existing traffic operations, identify future operations and determine the best intersection traffic control measures. The City’s goal was to produce high-quality design options that incorporated innovative corridor solutions.
Benesch developed a design to expand 13th Street to a 41-foot, three-lane road with five-foot sidewalks and curb and gutter. Improvements to 13th Street, a typical 24-foot asphalt roadway with minimal shoulders and drainage ditches, facilitates transportation for all users of the corridor in addition to adhering with the City’s complete street policy.
Prior to preliminary design, Benesch provided survey, geotechnical recommendations, utility coordination, traffic operations analysis and drainage analysis. The design took into consideration more than just widening the roadway. Other important design elements included storm drainage, ADA compliant ramps, pavement conditions, right-of-way and maintenance of access for the area’s residents and businesses.
During construction in the summer and fall of 2018, Benesch provided staking, construction observation and materials testing.
At the intersection of 13th Street and North Road, Benesch designed an offset roundabout. The roundabout helps manage area traffic and fits within the context of the existing residential corridor.
