The elevation of the Capri and Palms bridges will be about the same but the Capri bridge will be 27 feet longer than the Palms bridge.

TREASURE ISLAND – Residents of the Isle of Capri and Isle of Palms should see construction begin soon on the reconstruction of two bridges leading out to the two island neighborhoods.
Treasure Island City commissioners decided Oct. 3 to award a $3.465 million design-build contract to Johnson Brothers/A2B Engineering for the two bridges, which will be built concurrently and completed in mid-August.
A final vote on the bid award will come at the Oct. 16 City Commission meeting.
EC Driver and Associates, the city’s owner’s engineer for the project, selected Johnson Brothers/A2B Engineering over three other bidding companies based on its bid amount, the projected 298 calendar days to finish the project and its technical score.
The two bridges will feature 15-foot wide travel lanes and 6-foot wide sidewalks in both directions. Both will be mesa beige in color.
“The color will match the Central Beach Trail and Bascule Bridge,” said Greg Cutrone, a senior project engineer with A2B Engineering. “We’ll also have stamped concrete sidewalks to match the existing brick paver streetscape and lighted walkways at night.”
Plans call for one lane of each bridge to be completed in the first phase, which begins in December, and the other lane to be done in the second phase, beginning in April.
One lane of each bridge will be open at all times. Traffic flow will be controlled by portable signals at both ends of the bridges.
“Phase one provides for construction of the southern half of the bridge with traffic on the north,” said Cutrone. “We would then switch in phase two and would provide construction on the north side of the bridges with travel on the south side. And the traffic control system will always maintain at least one lane of two-way traffic.”
If needed during daytime peak hours, a flagman will be used to keep traffic moving effectively. One sidewalk will always be open to accommodate pedestrians.
Cutrone said the warranty on the pavement would be five years and the lighting for seven years.
