<br />ROADWAY MODIFICATION <br />There will be roadway modifications required <br />including sidewalk modifications, curb return <br />and ADA upgrades, median revisions to <br />discourage jaywalking, as well as, the temporary <br />demolition and reconstruction of the median to <br />accommodate the temporary traffic control <br />phases. The current median roadway geometry <br />allows for a comfortable U-Turn. <br />SIGNALS <br />Bridge mounted traffic signal heads will be <br />provided since the existing signal at 174th Street <br />will be obstructed by the new bridge. Miami- <br />Dade County only allows traffic signals to be <br />installed horizontally. A 17.5-foot vertical <br />clearance to the signal head is required. All signal <br />plans will be submitted to FDOT and Miami-Dade <br />County for approval. <br /> <br />Median on Collins Ave at 174th St <br />Signals at 174th St
