Clearing the streets of Gotham City requires dismantling the Arkham Knight's military infrastructure, which heavily occupies Miagani Island. As part of the Own the Roads side mission, players must locate and neutralize several heavily fortified militia roadblocks scattered across this neon-lit district. Successfully securing these zones helps the GCPD regain control and allows for safer Batmobile traversal throughout the late-game stages.

Northern Barricades Near Bristol Bridge

The northern sector of the island contains highly visible security gates designed to bottleneck local traffic and restrict access to neighboring boroughs. One prominent fortification sits directly at the foot of Bristol Bridge, blocking the main highway with heavy automated turrets. Players should approach from the rooftops to disable the scanning equipment before engaging the ground forces directly.

Another strategic roadblock is positioned near the botanical gardens, tucked away in a narrow alleyway that shields the militia from aerial view. This specific location features a mix of armed brutes and tactical commandos that require careful combat sequencing to defeat efficiently. Disrupting their communications array early in the fight prevents local drone support from arriving on the scene.

Central Fortifications Around Grand Avenue

The bustling commercial hub surrounding Grand Avenue is heavily occupied by advanced military checkpoints that restrict movement near major skyscrapers. A massive multi-layered blockade cuts off the main plaza, guarded by numerous armed soldiers and deployable automated watchtowers. Utilizing the Batmobile's remote combat capabilities is essential for tearing down these reinforced defensive structures safely.

Just a few blocks away, an elevated courtyard serves as a hidden staging ground for the Arkham Knight's elite peacekeeping units. This zone is heavily booby-trapped with proximity mines that can severely damage players who rush in without proper reconnaissance. Scanning the perimeter with Detective Mode will reveal the locations of these explosive devices and provide a safer path to the central terminal.

Southern Checkpoints Near the Ferris Wheel

The southern coastline features several isolated roadblocks that monitor the waterways and dockyards near the iconic amusement park structures. One terminal is positioned right outside the shipping yard entrance, utilizing dense metal barricades to prevent vehicular entry from the main road. Dismantling this site opens up vital shortcuts that make navigating the southern half of the island significantly faster.

The final barricade in this region is nestled near the base of the massive bridge leading toward Founders Island. This location is particularly dangerous due to the presence of multiple combat medics who can revive fallen militia members during the skirmish. Eliminating these specialized high-priority targets first ensures the roadblock remains permanently neutralized once the dust settles.
