2020) will add a total of four direct connectors: two from northbound Tomball Tollway to east and westbound SH 99 (Grand Parkway), with the other two connecting to southbound Tomball Tollway from east and westbound SH 99. Ramps from SH 99 to southbound Tomball Tollway opened in July 2022; Tomball Tollway ramps to SH 99 remain under construction. Increased capacity of existing toll roads Added capacity is planned for the following existing tollway segments: Sam Houston Tollway Southeast from SH 288 to IH 45 South: Two lanes will be added in each direction with improvements to the mainline toll plaza, and will have reconstructed entrance/exit ramps. Schematic design has been completed, construction is expected to begin in approximately 2 years. As of late 2015 the construction has not commenced since the interchange at SH288 has not been finalized where both TxDOT and HCTRA are finalizing plans for both the tollway upgrade and SH288 managed lanes. The first phase which commenced in 2015 is the construction of new overpasses for the west and eastbound Beltway 8 service lanes over a railroad right of way which parallels Mykawa Road (since the 1997 opening of the Sam Houston Tollway East one eastbound lane over Mykawa Road is co-shared with Beltway 8 where the realignment of the service lanes will eliminate the co-sharing with HCTRA and TxDOT (prior to the right of way co-sharing those who used the Beltway 8 service lanes had to make a turn on Mykawa Road and a left on Knapp Road in Pearland, TX where it had a surface crossing at a railroad right of way, which has been decommissioned later replaced with a flyover on McHard Road a few miles south during the early 2000s); this section of the tollway is congested on weekends where Cole's Flea Market is located south of the tollway on State Highway 35 in Pearland). Sam Houston Tollway East from IH 45 South to SH 225: One or two lanes are to be added in each direction with improvements to the mainline toll plaza, and will have reconstructed entrance/exit ramps. Construction for the tollway lanes is expected to begin in 2017. Sam Houston Tollway - Ship Channel Bridge from SH 225 to IH 10 East: A second span will be constructed over the Ship Channel with three or four lanes with full shoulders in each direction. Construction is expected to begin in 2018.
