Mesquite, Texas - The rebuilding of Tripp Road was spurred by a plea from residents of Mesquite who wanted a better-functioning multi-lane road and a safer street to use. The heavily used cross-street had only two lanes and no turn lanes, sidewalks or curbs. The city developed engineering plans to reconstruct the road, including paving, drainage, water, sanitary sewer and aesthetic improvements.
As part of the road improvement project, consulting engineer Kimley-Horn and Associates, Inc. was looking for an aesthetic bridge to span North Mesquite Creek. The structure would be part of a 'gateway' feature the city wanted for the Beltline Road/Tripp Road intersection, which would include landscaping, hardscaping, irrigation and lighting.
A bridge that could include aesthetic enhancements was necessary to complement the other 'gateway' features of the area. A multiple span CON/SPAN precast arch bridge was selected both for the aesthetic arch shape and its potential for additional architectural treatment on its headwalls. Design of the structure included unique ‘pie-shaped’ units to fit the site.
“The roadway was straight but the stream crossed at a skew,” said Brad Tribble, PE, of Kimley-Horn and Associates, Inc. “So we had to skew the CON/SPAN (units) - therefore the pie shapes on the ends.”
The seven precast cells each have a 36’ span and 9’ rise, with a length of 75’-10”. Installation of the 105 precast arches was completed in just 4 ½ days by general contractor Rebcon, Inc. Two skewed pieces were installed at the end of each cell and drilled shafts were utilized to support the structure.
The precast arches were faced with an applied stone. Pilasters were also included and lighting will be installed on top of the structure to add to the aesthetics. Owner:
