Bicycle and Micromobility Access

Bike lanes and shared paths are routes too. When work closes or crosses them, cyclists and micromobility users need a planned way through — not a sudden merge into traffic or a trench across their path.

Last reviewed: June 24, 2026

Why It Matters

  • Closing a bike lane without a plan forces cyclists into a live traffic lane at the worst possible point, and steel plates, trenches, and debris are serious hazards for narrow tires.
  • E-bikes and scooters share these routes and face the same hazards at higher speed.

When It Applies

  • Whenever work closes, narrows, or crosses a bike lane, protected bikeway, or shared-use path.

Planning Considerations

  • Plan a temporary bicycle route or a controlled merge, with adequate separation and clear signing, rather than an abrupt drop into traffic.
  • Plan for surface hazards — steel plates, trenches, gaps, and debris — that affect two-wheeled users.

Field Considerations

  • Provide the planned route or merge, keep the surface rideable, and keep steel plates ramped and secured and trenches covered.
  • Maintain nighttime visibility of the route and any hazards.

Inspection Considerations

  • Inspectors confirm cyclists have a planned, signed route or merge, that surfaces are rideable, and that hazards are controlled.

Common Compliance Failures

  • Bike lane closed with no route, dropping cyclists into traffic.
  • Steel plates, trenches, or debris left as hazards in the bicycle path.

Upstream Prevention

  • Plan the temporary bicycle route, separation, and surface treatment before closing a bikeway.
  • Verify bicycle-facility requirements with the governing agency.

Frequently Asked Questions

How are bicyclists handled in a work zone?

When a bike lane or shared route is affected, riders need a safe way past — a maintained bike route, a marked detour, or guidance to share a lane where that fits. The approach comes from the standard and the approved plan.

Can a work zone close a bike lane without an alternative?

Closing a bike lane generally requires providing for bicyclists rather than leaving them without a route. What is required depends on the road, the agency, and the approved plan.
