The I-35W/Crosstown Commons Area is heavily congested, has high crash rates and requires weaving between lanes. After several years of design setbacks due to unacceptable traffic closure periods, the Minnesota DOT pursued precast segmental alternatives in order to minimize erection times and traffic closures. Closures for major movements during construction were estimated to be no longer than two months.
Hatcher Technical worked with construction engineer McNary Bergeron to provide:
- Fully integrated shop drawings for precast superstructure segments across 6 bridges
