• Ham Beringen Highway Highway E313 (Ham - Beringen)
  
  Based on the project documentation, here's a summary of the work completed:
  
  Project Scope
  
  1. Emergency Lane Conversion (Km 50.0 - Km 57.7)
  - Converted the emergency lane into a rush-hour traffic lane (spitsstrook)
  - Designed emergency refuges (pechhaven) every 500m, measuring 100m long × 4m wide
  - Installed portal structures every 500m to inform drivers when the new lane is open or closed
  - Added portals at highway entrances and exits
  
  2. Highway Access Modification (Km 51.2)
  - Redesigned the highway entrance ramp to comply with current safety regulations
  - Demolished the old access route and replaced it with green space
  - Created new access alignments meeting modern traffic safety requirements
  
  ## Design Challenges & Solutions
  
  Lane Design:
  - Sketched lanes with appropriate widths based on design speeds
  - Carefully measured lane widths considering marking line types (interrupted vs. continuous)
  - Designed alignment using clothoid curves for the highway access at 50 km/h and 70 km/h design speeds
  
  Safety Zone Analysis:
  - Determined veiligheidsstrook (safety zone) requirements
  - Assessed when guardrails (vangrail/geleiderail) or concrete barriers (New Jersey) were needed
  - Selected appropriate barrier resistance levels (H2) and working widths (W6)
  - Positioned barriers considering minimum distances from travel lanes (objectafstand)
  - Calculated minimum barrier lengths (105m: 2/3 before, 1/3 after obstacles)
  
  Road Markings:
  - Designed road markings per Belgian standards for:
  - Lane delineation
  - Highway entrance/exit zones
  - No-traffic zones
  - Bifurcations
  
  Deliverables:
  
  - Existing conditions plans (including demolition elements)
  - Utility plans
  - Proposed layout plans
  - Typical cross-sections
  - Alignment plans for highway entrance
  - Characteristic profiles (sections)
  - Traffic signage plans
  - Drainage plans
  - Construction details (reinforcement plans for rigid/flexible pavement connections)
  - Legends
