Because of multiple accidents at Watts Plantation and Sienna Parkway, Missouri City will initiate the following safety measures in the next few weeks:
*Install a prohibitive left turn movement from westbound Watts Plantation onto southbound Sienna Pkwy; *Allow an eastbound left turn movement from Sienna Pkwy to Watts Plantation; *Prohibit U-turn movements at two median openings just north of the Watts Plantation/Sienna Pkwy intersection; *Allow U-turns at the protected left signal at Sienna Pkwy and Sienna Springs; and *Install a flexible curb system, add pavement markings, and add signage at the Watts Plantation/Sienna Pkwy intersection to ensure visibility and improve warning.
Prior to median closures, the city also will implement the following cut-through traffic prohibition:
*Install selected striping on Diamond Springs Drive to establish a definitive two-lane neighborhood street.
Police patrol units will be on-hand in the first weeks of the median closures to monitor traffic and deter speeding.
The recent multiple accidents led Missouri City to commission a traffic engineering analysis to evaluate accident history for the past three years. The analysis considered turning movements, sight distance, existing roadway geometrics and potential traffic calming measures. The impending extension of Fort Bend Parkway in the near future to intersect with Sienna Parkway was also considered.
The city will monitor traffic patterns at the above intersection and at Silver Ridge Blvd. before and after the implementation to see if other mitigation efforts are needed.
The city regrets motorist inconvenience but believes motorist safety comes first.
