Travel on the Intercounty Connector is about to speed up. The Maryland Transportation Authority plans to install new speed limit signs on Friday and Saturday, formally increasing the roadway’s speed limit to 60 mph from the current 55 mph limit.

Signs will be posted on the westbound lanes on Friday, while they will be added to the eastbound lanes on Saturday. In addition, drivers will see new warning signs for curves.

The authority first announced the change last month, following an engineering study that said the speed limit could be safely increased.

Drivers should save about 90 seconds of travel time, according to the authority. The ICC was designed for vehicles traveling 60 mph.
