Seminole County, Florida, has an extensive system of walking and bicycle trails. The Cross Seminole Trail is being developed to provide a trail that goes east and west across the county, and connects the major north south trail along the old Orange Belt Railroad to trails south and east in Orange County.

The biggest obstacle in building the Cross Seminole Trail is finding a safe way to cross Interstate Highway 4. The trail was routed over a highway overpass, but it was a difficult crossing due to the large volume of traffic in this area. A need was recognized to build a dedicated trail overpass. A cable stayed design was picked to avoid having to place any structure within the right-of-way on I-4. This lead to the 373 foot long clear span over the highway.

The photo above is looking east at the south face of the Cross Seminole Trail Overpass. The photo below is looking east along the south face of the structure from the ramp leading to the west end of the bridge.

These two photos are detail views of the cable attachments. The photo above is a cable attachment on the bridge anchor block. The photo below is a cable attachment on the main bridge span. The anchor block attachments hold the main tower in position and balance the forces from the cables supporting the suspended span.

These two photos are similar views of the north face of the bridge as seen from the ramp on the east side of the I-4 highway crossing. The photo above is a view of the east bridge tower. The photo below is a view of the entire suspended span. Note that the ramps make a loop and pass under the bridge deck between the anchor block and support tower.

The photo above is a detail view of the cable anchors at the top of the west bridge tower. Note that there are 3 cables leading down to each side of the anchor block, while there are 6 cables attached to each side of the suspended span. The photo below is an overhead view of the bridge that has been clipped from an Internet mapping service. Note that the highway lane configuration is different in this view. The highway has 4 lanes in each direction in these 2010 photos, but the photo below shows 3 lanes southbound, and 6 lanes northbound. I suspect that the highway is being rebuilt in the photos below, and that the southbound lanes have been (or will be) diverted to the 3 unused lanes on the right side of the median.
