FM518/Broadway overpass at FM521/UPRR
Fort Bend County
FM 521/West Broadway/Lake Olympia Parkway
At FM 518
Existing Broadway/Lake Olympia have an at-grade intersection with FM 521 and crossing of the UPRR. The connection of Lake Olympia Parkway westward to the Fort Bend Parkway and beyond will significantly increase traffic volumes which will add to delays, emissions and safety risks crossing the UPRR and at the intersection with FM 521.
The proposed project is construction of a 4-lane overpass, approach roadways and loop ramps connecting to FM 521 which will provide a grade separated crossing of FM 521 and the UPRR.
The grade separation will improve safety for all vehicles using the overpass, reduce emissions and delays. Additional benefits will accrue to users of FM 521 as the reduction in traffic on Broadway/Lake Olympia intersecting with FM 521 will reduce delays and emissions along FM 521 will improving safety.
