# Median U-Turn (MUT)

An intersection where left-turn movements from both the major and minor approaches are removed from the main crossing and rerouted through a downstream median crossover, requiring a driver to travel past the intersection, make a U-turn, then complete the turn from the opposite direction.

Safe By Design

This video explains how the Restricted Crossing U-Turn removes left turns and crossing movements from the side street, with crash-reduction results from Alabama, Nebraska and North Carolina and an honest look at the longer pedestrian crossings it can create. It is a close companion to the Commonway System's RCUT pattern and retrofit strategy, and to the related Median U-Turn and Displaced Left-Turn designs.

Compact is an edge case. Urban and Core are unlikely pairings.

## Design notes

This geometry exists to remove unprotected left turns from a major intersection entirely, rather than managing them with a longer signal phase.[1] Doing so shortens the signal cycle the main intersection needs to run and reduces the conflict points a driver has to judge in a single movement.[2] The tradeoff is a longer path for the rerouted turn and the median width needed to accommodate it, which is why this pattern is Situational rather than broadly Recommended: it solves a real problem well on a wide, higher-speed divided road, but doesn't fit a narrower cross-section or a genuinely low-speed context where Roundabout or a conventional Signal remains the better fit.

-   [Displaced Left-Turn](https://commonwaysystem.org/patterns/intersections/displaced-left-turn.md) (INT-DLT-14) (an alternative approach to the same unprotected-left-turn problem)
-   [Signal](https://commonwaysystem.org/patterns/intersections/signal.md) (INT-SIG-03) (the conventional intersection this pattern modifies rather than replaces outright)

## Getting there: Retrofit path options

[Median U-Turn (MUT) retrofit](https://commonwaysystem.org/retrofits/intersection/median-u-turn-mut-retrofit.md) (RFT-INT-02) reroutes an existing conventional intersection's left-turn and through movements to this geometry.
