 The widest right-of-way, , occurs at the Katy Freeway's intersection with Bunker Hill; at that point, the expansion plans called for six main lanes plus two toll lanes in each direction along with 10 lanes on the feeder/frontage roads.The actual striping after construction delineates 29 lanes, including all 26 of the planned lanes plus an additional lane in each direction to enter or exit the toll lanes and one more turn lane on the eastbound feeder road.Between I-610 and I-45 west of downtown, the interstate contains at least five main lanes in each direction.
