# Can a modular joint be field spliced at every lane line?

## D.S. Brown Steelflex® Modular Expansion Joint Systems have gained overwhelming worldwide acceptance for accommodating and sealing large joint movements on bridge structures.

**Answer:** No, field splicing a modular joint at every lane line is not recommended, effective or economical. Field splices should be used sparingly and located in non-traffic areas whenever possible. Additionally, bolted field splice connections are not recommended either due to fatigue issues.

Since the early 1960s The D.S. Brown Company has provided [expansion joint systems](https://www.dsbrown.com/product-category/bridges/expansion-joint-systems/) and structural bearing assemblies for bridges around the globe. Bridge expansion joint systems are directly exposed to vehicular wheel loads and, therefore, must resist dynamic forces causing fatigue and wear. In addition, these expansion joint systems must remain watertight to protect the bridge superstructure and substructure from corrosion.
