ends west of Avocado Avenue, but begins again before it turns south onto South French Avenue. During this triple-concurrency, US 17-92-SR 46 intersects a pair of railroad crossings at a junction of two freight lines, and then another one at the intersection of West 13th Street, also the western terminus of County Road 415. SR 46 then branches off to the east again at H.E. Thomas Jr. Parkway (County Road 46A) and 25th Street. SR 46 runs along the northern border of the Orlando Sanford International Airport, then after the southern terminus of State Road 415, uses a bridge over Lake Jesup at the St. Johns River then become Geneva Avenue as it heads southeast. East of Geneva, the road crosses the St. Johns River itself using the Mims Bridge south of Lake Harney, and entering Volusia County. The journey through Volusia is short-lived though, because the road quickly enters Brevard County and turns straight east at Southmere, where it becomes Carpenter Road. SR 46 finally enters Mims in the vicinity of Interstate 95 at Exit 223, and then ends at US 1. History The intersection at the western terminus of State Route 46 and US 441 was previously a diamond interchange, but was downgraded as part of the Wekiva Parkway project. County Road 46A previously cut through a portion of the Seminole State Forest and met State Road 46 further east, but was realigned to meet State Road 46 west of it to reduce its impact. Between State Road 429 and the Lake-Seminole County Line, State Road 46 was realigned to follow the future alignment of State Road 429, resulting in a few segments of highway being bypassed and orphaned. Future SR 46 will be truncated at its interchanges with SR 453 and SR 429 when the Wekiva Parkway project is completed in 2022, resulting in two discontinuous segments.
