ORIGINAL ACCOUNT · UNDATED SOURCE
The wording, dates and project status below are preserved from the historical page.
Beltway 8 has an outstanding collection of modern 4 and 5 level stacks - possibly the best in the country. The only competitor for that honor is the Century Freeway in Los Angeles. Beltway 8 is unique in that the feeder roads for both BW8 and intersecting freeways proceed underneath all the stacks, either at grade or one level below grade. The order of stacking is (from the lowest upward): feeders, intersecting freeway, BW8, direct connectors, direct connectors.
It should be noted that although there are four complete 5-level stacks and one under construction, the ramps typically do not intersect over a single point. This means that level 5, for example, may cross the level 4 ramps and a point where level 4 is not at its highest point. Nevertheless, Beltway 8 still has some of the highest and most massive connection ramps anywhere. Houston stacks are not sleek and beautiful like California stacks (the Century Freeway in particular), but if you like massive concrete and steel, you'll love the Beltway 8 stacks.
There's more stack construction underway and planned (see map).
