Revise initial line and grade for intermediate (50%) design
Begin intermediate design by further revising the line and grade along with the accompanying design elements:
- Incorporate comments from 30% review
- Develop responses to 30% review comments
- Update Typical Sections
- Update Roadway geometric design
- Develop approach road design
- Develop pullouts and parking area design
- Develop' worst case' construction and clearing limits
Step 1: Incorporate comments from 30% review
| Instructions | Resources | References |
